The most recent update broke the widget... the widget is completely blank now and I have to click into the app to see what my numbers are.

The widget chart over the past few weeks prior to this update was also incorrect. The line on the chart would be 3 hours in the past rather than the current line. For example, it would appear that I was dipping low, but if I looked at the app, it would show that I was dipping low 3 hours ago and was currently 145 and steady.

Also, every single time I get a low alert, double alerts come through in slightly different sounding tones. It will make the noise and say I'm 66 ↘️, then .5 seconds later it will make the noise again and say I'm 66↘️...both alerts wanting me to acknowledge them on the screen.

It's extremely difficult to log the amount of time you're doing a workout. It requires a lot of precision to get to the right number. Also, it really annoys me that it won't let you move the time to the future. I would like to log things accurately, but if it's 4:20 and I'm at a yoga class that starts at 4:30, it won't let me say my activity starts at 4:30. It will only let me put 4:20 as the start time. The odds of me remembering to go back and input it after the workout is over are slim.

I like that they've attempted to add clarity info into the app, but it's very buggy. It takes ages to load, and often refuses to load anything for certain time periods, like 90 days, even though I've worn g7 since May 2023.

Cannot dismiss alerts from watch

This app is almost good. It’s missing two features that are standard in every other app in the AppStore. And with those features it would be 4 stars.
1. Most important. Be able to dismiss alerts from the Apple Watch. I get alert, dismiss the alert of the watch, but a minute later it alerts again. Making me have to open the app on my phone to dismiss the alert. If I’m in a meeting or somewhere important I can’t be pulling out my phone or having Loud critical alerts going off every couple of minutes for something I’ve taken care of. An even better feature would be to let me get a 1 minute quiet notification on my watch that I could clear before even setting off a critical alert. But as the way it is now, I’m going to have to turn off critical alert notifications, which is not a good thing.
2. This doesn’t seem like a big one, but it is. Dark mode. It exists on Dexcom Follow app, so I know there Devs know how to do it, and they should be using shared libraries, so why am I blinding my self at night to check my Blood Sugars? A device and technology so advanced it can tell me my blood sugar every 5 minutes just by looking at a screen, when just 20 years ago we were peeing on sticks, and not long before that peeing on the ground and watching for ants. But yet my retinas burn when I check my blood sugar. And my I get just as embarrassed as everyone stares at me thinking I didn’t mute my phone for the meeting. Please fix this.

Useless app from overseas

I used the G6 app during my travels, the G7 app cannot be setup from overseas, even if your residence is in the US. To start you are forced to allow access to location services ( setup screen locked until location access is granted), which in itself is an invasion of privacy. Then, contrary to the disclaimer, the location is used for comparison with the account address and the setup Is locked with an error indicating location different from residence as if one has to be locked in one’s residence. An invitation to contact technical support yields no result beside waste of communication fees from abroad ( delete and reload, create new account… ) and confusing explanations about geolocation allegedly not working in every country. It might be time for US developers to realize that the world extends beyond San Diego and Boston ! One thing is sure, on my return to the US, once my nine sensors are used up I will switch to another CGM ( FreeStyle Libre) or no CGM For US companies and software developers to be so dismissive of the rest of the world in 2024 is beyond belief!
Contact suggested by Apple does not yield any result , the only suggestion by Dexcom support is to buy the receiver and basically not use / initialise the app while overseas. This is beyond belief in an allegedly global world!!!
The western world view is anyone outside the west is a thief or a fraud and everything must be done to restrict or suppress his access! Pathetic!
