[com.ebay.kleinanzeigen] app stuck on opening links since 0.3.6

[D1795]

Name: Kleinanzeigen
Package id: com.ebay.kleinanzeigen

Describe the bug
Opening a link to Kleinanzeigen which should open the app doesn't work. The app stuck at the start-symbol

To Reproduce
Steps to reproduce the behavior:
Set the app to open Kleinanzeigen links by default.
Klick any link to Kleinanzeigen

Expected behavior
The app should open like it did before.

System
Android Version: Tested on A12 and A13
Custom ROM: CrDroid 8 and CrDroid 9

microG
microG Core version: 0.3.6.244735
microG Self-Check results: not all ticked on A12 (because of new spoofing problem, was ticked before, everything working)
All ticked on A13 with fakegapps

Came from 0.2.8, so don't know if any of the versions in between would also cause the problem.

Updating Kleinanzeigen to newest version didn't change the behavior.
