App unusable, does not find any PKPASS files beyond the one loaded first

[leehyunkeun]

Setup: Version 3.7.3 on an unrooted Android 9 device with all necessary permissions granted.

Issue: The search function (tap on "+" symbol > "Suche nach pkpass Dateien") does not work at all. Even when placing multiple PKPASS files in the default search path (/storage/emulated/0/Download), only a single PKPASS file is found, namely the very first one that was loaded into the app after installation. The app appears to store a copy of that first PKPASS file somewhere and does not actually search for files anywhere else, not even inside the displayed default search path. This renders the app effectively unusable, as one is stuck with a single PKPASS file that cannot be replaced or updated.
