You killed “Calendar” app

I’m not sure what you’re doing every time I pull up the Apple calendar app but you’ve destroyed it’s ability to render correctly. Must you recheck all the link in calendar every time I open it (I think this is what is happening). I live in the calendar app with managing 5+ different calendars between a busy work life, teenagers, service work and a marriage. Please figure this out for better functionality. If you’re going to sell companies on that they need to force employees to put this on personal devices then stop ruining their personal device experience.

READ: Battery Usage and link scans and network usage

I’ve seen a significant amount of reviews complaining about “High battery usage” and “5k links?? I only used one app!” iOS tracks “battery usage” based on network activity, and because this acts as a VPN, yes, it will show high battery usage, but in reality it’s not. Let’s say Facebook used 10% battery, and Instagram used 15% battery, after installing this app, you’d see iOS report that this app used 25% of your battery. I’m sure you get the idea now. You can validate this information by using any VPN client on your phone. Link scans: This is all traffic from your phone: background app refreshes, apps can send request to hundreds of separate links. That’s why you see so many link scans.

Network usage: again, because all apps route their data into this app, your data usage will be pointed to this app aswell. If you used 5GB on Facebook, it would show as 5GB under this app.

Good overall app, for all your devices. The vpn option stopped working after I upgraded to ios 16 for some reason. Even though the iPhone shows the vpn icon, and it shows it’s connected in the settings but there’s no vpn server. I maybe missing something but not using for now….

vpn is working again. Updating to 4 star. For several days a lot of iPhones/MacBook users did not have vpn, even though their iPhone showed they did. Back to using the app
