Thank you very much for your input, especially about the calendar, that points me to the fact I have yet to see if every other member of our family is ok with moving mail under Proton.

As for the gaming I have explained myself poorly (sorry about that) - the connectivity concern was aimed at multiplayer gaming while using VPN. While I understand some titles are not suitable for the use of VPN at all, I suppose ordinary disconnections can happen with VPN. That was what I tried to write :)

Thank you again!
