New user about to jump into Proton

Hello everyone,

I am very new and recently have decided to move away our growing home/work network away from Google and also increase our digital security. I got recommended to try Proton as it is (as I understand) a full suite of feature we would use (be it mail, productivity apps, vpn, authenticator, cloud) but seeing some of the reactions here, I am concerned.

Are there any really grave concerns about Proton or any substantial flaws I should be aware of as a new user? I also got some mixed reviews about unstable gaming sessions (that would be a home disaster for the kids hehe) as it disconnects but I suppose that is a problem of the free limited VPN connecting to free servers.

Thank you in advance for any input.
