Summary

After downloading the latest version of the ProtonVPN app from the Proton website (version 2.3.12.0), I tried to install it. Alas, no success: at about three quarters of the installation process I get an error message stating 'App not installed' (while the previous version 2.2.3 was installed without any problem the day before).

• The bug is the source of a data loss or a big waste of time
• The bug concerns a third-party application
