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.

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
