Looking at their website I still can't figure out what plan you are on while still needing to pay for proton pass. The only plan I see that matches your $120/year (USD, I'm from the US) comment and matches your "more than 3 custom email domains" is the proton business tier which is $13-10/month depending on the number of months you purchase in advance. And in all cases you once again get access to all other proton apps and their premium services for free. Sounds like maybe you're on some legacy plan and would benefit (probably save money?) by going onto one of their new pricing structures? Not sure because I got upgraded to an unlimited plan for free back in the day (since i started when they only offered email) and so I'm still grandfathered in to a better price than is currently possible that includes everything.
It's unfortunate their android app seems to be 2nd class to their iOS offerings; sadly that's fairly commonplace, especially with small teams on tight budgets. I imagine that's also why their proton pass pricing is so expensive.
But once again, I don't see a need to slander and lie about a company that by all accounts is trying to actually do something about the privacy nightmare that the internet has become.
