I've been having a similar issue for about a week, maybe two. It'll work for about 2-3 days without issue, then randomly nothing works anymore and I get messages about failing to get data and whatnot, depending on what I was trying to do. This is the first time this issue has occurred in the ~2 years I've had my lights.
However, there may be an easier way to get your stuff to work again (OP) without having to uninstall the app & reinstall it... if you haven't already tried this of course.
**This works for me, curious to see if it'll help you &/or anyone else...
-In the app (Android), at the bottom of it's 'home' screen, tap "Account";
-Then tap "Account >"
-Tap "Sign out" (should refresh to the sign in screen)
-Sign back in. (I got tired of entering this info, so I save my login credentials to Google and just use my thumbprint now)
That's it. That's all I have to do to get it working again.... for another 3 days-ish, I honestly haven't paid that much attention to it to know for sure. I'm also assuming you'll probably have to sign out of the account/accounts on all phones/tablets.
If it works, it should be faster than uninstalling and reinstalling, plus you wont have to set everything up again (rules/groups/etc). I DO however have to re-order the lights in my groups... I named them like Desk Left & Desk Right, and the left and right get swapped as far as how they're listed in the "group".
All I can add to the issue/bug report is that I usually leave the app running on my phone. I only have a couple bulbs but don't alter them but a couple times throughout the morning or evening.
App is v3.2.2.441
Samsung Galaxy S22 Ultra (SM-S908U)
Android 14 (w/One UI 6.1)
