I’m having the same issue.
It appears the the SNAP server is in Michigan(??) and FB is closing the session when I’m logged in from my home in Florida.
FB then “locked” my account.
I finally got it back on…but this seems VERY dangerous.
I’m running MANY sites using SNAP (with many licenses), and they are all starting to see the same behavior.
Is this fixable, or is SNAP dead now???
