I’m not getting emails anymore I think someone hacked me n fitv

You think someone hacked you apparently. and you post a bunch of headers from a mail from Proton support about some bug in their product from an iphone. There is no Thunderbird for iphone. The email does not look like something from Thunderbird at all. The header contains details of a specific zendesk account and the email is sent to a proton.me account by proton support. So can we start again. What is the problem? and what does Thunderbird have to do with this at all.
