The specifications are such that the app can be viewed without the user logging in.
However, I want to allow only registered / logged-in users to register favorites and edit profiles.
In my case, I want to change the page transition destination depending on whether I am logged in or not. What should I do after “When does this happen?” “Sometimes …”?
To achieve this you can use 2 conditional actions with different transition animations: one action will happen if Logged-In User → Email is NOT EQUAL to empty (for logged-in users), and the other one will happen if Logged-In User → Email is EQUAL to empty (for guests).
The workaround that Victor described above (conditions) worked for me Just need to set actions depending if the user is/not logged in and move them to relevant screens
