Not sure if this is by design or a bug
Mobile app on android constantly logs out and no way to remember any details - very annoying to have to retype my somewhat long email address and PW all the time.
Be nice if the app stayed logged in (or had a choice to stay logged in or remember details)
it is security feature, but the time interval is quite long and most of the android save your email_id in auto correct and suggest you when the first letter is typed.
Mine remembers the email for EVERY.OTHER.APP apart from cayenne 
. I find i’m logging in twice a day which is annoying but not the end of world #firstworldproblems
what is the app version you are using?
