Both auto-forwarding and auto-reply are paid features, which makes cancelling & switching much more difficult. Gmail is a breeze comparatively. I highly recommend against using their addresses (e.g. protonmail.com, proton.me, pm.me)
Email forwarding is available for everyone with a paid Proton Mail plan.

You do not have to care. I’m only highlighting that according to this community your post is precisely not “informing” much.
Also while checking your history https://lemmy.ml/post/19526546 it seems to be a pattern of misunderstanding then blaming it on others.
I guess that’s what not arguing over petty details like “technical definitions” might result in.
Please do not use Proton if you do not think it’s appropriate for your usage. Please do inform others about problems you do encounter. Please do note though that when you are misrepresenting the situation, e.g. with titles that are shortcuts and thus incorrect, you are NOT helping.
