Just want to point out something fairly obvious, but --
AquaMail does not cause any trouble in Norton or LastPass or 1Pass.
Norton and LastPass and 1Pass *may* (on some devices, for some users... not on my phones, unfortunately) -- break AquaMail, and, based on Play comments under LastPass, other apps as well.
Based on the above, it has to be fixed in Norton / LastPass / 1Pass / Android itself (haha, good luck, Mr. Gorsky) -- but I'm afraid all those fine developers just don't give a rat's ass about breaking other apps.
