Seems to readily impact 50% of the entire function of an email app (to write emails).
Seems like a weird hill for Proton to not want to climb down, considering their position within the email client marketplace. I would absolutely make UX a high priority.
Considering the purpose of Tensor, I’m sure it’s a lot faster on phones with tensor chips.
They probably just need time to speed it up for older phones - which is just fine for them because of the business impacts.
