Unable to download the latest update on iOS 15 Pro

Unable to download the latest update of the App. Tried deleting the app, restarted the phone multiple times and different networks with no success.

Update broke the app on Day 2

I only got to use Lief for 1 day before version 8.1 bricked it. Now it’s stuck on the pulsing screen and won’t connect on either iPhone or Mac. Please fix ASAP — I’ll update this review once it works again.
