Started receiving an unexpected message after updating apps via APK files. Most recently this occurred with the Proton VPN app.
After downloading the latest version directly from the Proton VPN website, I launch the APK and the usual system message appears: Do you want to install this app? Proton VPN is shown.
Once the app has been updated, the system message App installed is displayed, however, the application name shows as com.protonvpn.android.ProtonApplicationHilt.
When examining the Proton VPN app by accessing Settings > Apps > Proton VPN, the app correctly displays as ch.protonvpn.android, and the version number was correctly updated. When examining the list of all apps installed (with Show System apps enabled), there is no app by the name of com.protonvpn.android.ProtonApplicationHilt, hence my confusion.
To clarify, the APK was downloaded from the official Proton VPN website. Thoughts as to why this behaviour is occurring?
