Changing zone temperature crashes Honeywell android app

[MrBoy]

Whenever I go to change an EvoHome zone temperature in the android app, it shows me this success screen but then seems to hang:

If I don't quit, the app seems to automatically restart but that's not great. Are there known issues or am I doing something wrong?
