I already used my proton email as contact method on some published stuff that I can't modify. Do you have some tips for that situation, or am I stuck now?
I'd probably just set up a forwarding rule and call it good if you can't modify it.
Right now my Proton account has a few straggling outliers forwarding to my new accounts, but I've mostly switched everything over to emails that are for a domain I own so it's a little easier moving forward.
