App no longer works

I have two T6 Pro thermostats that have bee functioning flawlessly with the Honeywell Lyric app for last two years. Then last week noticed app no longer gave correct status readings ( showed units running when in fact they were off , and current and set temperature values were reversed). Checked for new updates but none available last week. Decided to delete one of the thermostats from app and add it again. Big mistake. I cannot get through the install process. App gets to point to select network name and then nothing. iPhone setting shows it available but no options from there. I have tried deleting the app, backup data, reset thermostat to factory settings, nothing seems to help get the app to add the device. Saw new version yesterday and downloaded it but same issue. Not supposed to be this difficult to work with an app. It is now Friday December 4, 1:30 pm central standard time and have been on hold on phone with customer support for 1 hour and 55 minutes with no indication when they will get to me or if there is even anyone at the office.
Not the kind of product behavior and customer support I expected.

Used to work great

They have updated this app recently, maybe the 2nd to the last update basically messed this app up. Like what the others are experiencing, the scheduling function has been a nightmare since. I used to be able to change it and it will follow the schedule properly (or even if I leave the schedule alone). Now, the schedule won’t change until you go to the app and close it, open it again and maybe if you are lucky it will show “following schedule”, otherwise, you have to close and reopen the app several times. It is always showing “no schedule”. Also, before when I click and adjust the temp, it will give me an option to either hold for a period of time, hold temporarily or remove hold, now it does not do that all the time, sometimes I click out of the main page where you adjust the temp and go back and it will show up, most of the time I have to close the app out a few times to be able to get these options to show up. Also, I did not change any of the settings in the app nor the thermostats and the only thing that I change constantly is the temp and schedule which I used to do all the time and the app always follows the schedule. Obviously something got messed up on the updates, I wish they leave the app alone, I understand that it is necessary for security purposes but sometimes if it ain’t broke don’t fix it. Do not need the bells and whistles, just app the works because it used to. Please fix the bugs soon, its a great app when it actually works.

Nice app and now it’s fast too

The app looks pretty good and setup was easy. Programming a schedule is a bit fidgety, but I don’t need to change it often so that’s fine. After that it runs the schedule and everything operates the way it should.

Update: The issue below was bothering me for months, but customer support had me delete and reinstall the app and that seems to have fixed it!

Original issue: The one big issue is that when I open the app it takes about 30 seconds to update to the current status of my T9 thermostat. Every once in a while it updates in just a couple seconds but usually it is slow. During that time, I have to keep the app open and just wait. If I switch to a different app and come back later it does not update in the background. If I quit the app completely and relaunch I still have to wait. So it does work, but it’s quite annoying when all I want to do is a quick status check or bump the temp up or down. I have a long delay where I just stare at out-of-date info and can’t use my phone.
