Michael,

It always helps to not assume anything and test everything. I have a 
modern smartphone get an OS update quarterly.  After each update, I get 
the same symptom... Every ~20 hours all applications send me 
notifications that I have to log in again.  However, when I check I am 
logged in.  The only cure I found was to wipe the phone clean and 
install each application again manually.  If I restore from backup the 
nonsense starts all over again.  It goes against reason but it happens 
reliably after each OS update.  Software is funny that way.
