I get that too, it can be difficult to get help. I try to ignore it and have been using Linux for about 15 years as an OS. I use Kubuntu on my laptop, but I've used Mint also. I'm thinking of changing back but it's so much work, and there are a lot of other options I'd like to try.

I've had my network locked out as well, the first iteration of ProtonVPN I used would lock it out if you didn't close the app before shutting down. I contacted Proton and they sent me the commands to unlock it, so I have them handy in a file. That problem was fixed, afaik, because I can shut down without exiting the app now. I haven't had my comp suspend, Linux used to have a problem with suspend so I've stayed away from it. I haven't had any problems with Proton otherwise, I used it on my Android as well, I have a paid plan.
