BNP Entreprise App not working anymore

I suspect a recent update of the BNP Entreprise App is not working any more on Murena Fairphone 4.
The package name is “” and the version is 3.2.0.
The error message is at startup after the screen shows:

“Somathing went wrong”
“Check that Google Play is enabled on your device and that you’re using an up-to-date version before opening the app. If the problem persist reinstall the app.”

reinstallation does not change anything.
Is there a way to downgrade the app in order to try an older version ?
