Homey app not working on iPhone 12 ios 15.5


I just got my Homey Pro back from storage and downloaded the Homey app on my iPhone 12, ios 15.5 (latest).

My user credentials work fine when log in at the Homey website, but there’s only a blanck screen on my phone. I’ve tried forced restart on the phone, deleted and reinstalled the Homey app and also turned 2 factor authentication on and off.

I have searched for a solution, but no luck so far.

I have attached a screenshot.

Any suggestions for a solution to this problem?

I got an Iphone 12 with IOS 15.5.
I have no problems with the Homey App.

What I did was restore the homey to factory settings. Then downloaded app on my iphone 12 mini and on my ipad mini 2. Login on my ipad is fine however not on my iphone. After entering the credentials the screen turns white.

iphone ios15.4.1
ipad ios 14.4.2

homey version 8.0.1

And when i press the back button, it ends up like this.
