I want to love this app and I have been using it for years but more and more they keep making changes and breaking the app. Half the time, I don't even get a notification, even though I have the app configured to be allowed in the background and all that jazz, unless I have my phone open and the app actively open, I will not receive a notification. Lately it's even worse, to the point where I'll get the notification and I'll click unlock but it fails with some unreadable message. Stop breaking.

It usually works eventually, but it's janky. You'll often open it only to find the Unlock feature missing—sometimes it shows up after a few seconds, sometimes you have to force kill the app and restart it. Even on an excellent connection (I'm in the middle of Manhattan) server delays are super noticeable making the UI bad. It feels like they're trying to render the UI based on what they receive from the server in terms of your access at time of load, but if so it's a mistake (and unsafe).

All of a sudden the app has stopped working on my google Pixel 7 Pro(I've been using this for work for 1 year). I have done everything to get it to work. Made sure the updates were up to date, uninstalled and re installed it, and rebooted my phone. I am the only person in out building that uses it that has a Pixel. I installed it to my ipad and have had no issues. I reached out to support and it's been 2 weeks and i still haven't gotten a follow up. Beware if you are anything, but and IOS user.
