i too miss the alias service, and i dont really know an alternative aswell.
The issue is kinda, that any alias service is basically just forwarding your mails … so it is really hard to trust anyone with that
and a private domain is not really a solution, for privacy
and like tuta does offer 15 or 30 (but 30 is super expensive) permanent aliases… which is like nice but does fill up super quickly if used like how it is used for proton
if you get youtube premium it should work fine 😬
if they did not change it
on your phone, does it also not work in browser if you are logged in?
