My guess is that when they decided to rewrite the web front-end in React, they also put off any major mobile updates until they could port the mobile apps to React too.
Hopefully there is a big mobile update coming soon now that ProtonMail 4.0 is out of beta.
Their mobile apps haven’t received any serious update for years, it’s frustrating indeed and there is no excuse. I plan to cancel my subscription next month and try something else. Privacy is good, but not by crippling productivity.
