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.

my beef with proton mail is that i can’t use it on thunderbird and their android app doesn’t have notifications (at least without google spy services.)
To get notifications using the Android app on a de-googled phone, you can use the app ‘You Have Mail’ available on F-Droid. It was developed to solve the issue you described.
I use it on Thunderbird. I just couldn’t grow to like thunderbird.
i couldn’t set it up and it went a little beyond my understanding why, but apparently it’s a paid feature. i don’t necessarily love thubderbird either, but it does its job for me
Thunderbird doesn’t have your private key to decrypt your Proton emails. The key lives in your browser and in theory there’s no way to securely provide that key to Thunderbird so it can do the decrypting. There’s a special application they built for business owners who want this functionality,
but by nature it breaks Proton’s security because the email content is then stored in plaintext (or close enough) so it’s not “secure” in the same sense Proton webmail is. (edit: maybe it got updates since I last looked, because the Bridge is now as secure as the webmail)You have to use the Proton Mail Bridge
