I muss say that I find the Duo mobile app pretty poor feature wise. I have about 40 services using it (either via Duo push or as “plain” OTP) and find it fairly unusable without a search function (how hard could it be to implement ?).
Also nice would be the possibility to create folders (to file into them). And last but not lest a seamless & working Duo Restore, across different devices & OS would be much appreciated
