Actually, clicking on default Logout button, keeps the currentUser content present. It is not wanted if you want to check visibility based on something like:
appVars.currentUser.username == "demo"
At logout logic, when adding "set app variable" currentUser = null (formula) it effectively dumps the user record and prevents visibility. BTW user auth presence should be easier :) But that's a deeper subject :) Thanks for AppGyver, I'll gyve back what I can and will gyve back feedback too. really hope to test PWA export soon!
