I have tried setting up SSIW on another iPhone to see if the investment of deleting the web history on my own phone has promise.
The same situation results which implies that all iPhone/ iPad users of SSIW are ‘half’ logged in with the new release.
I set up a new user and downloaded the App to the phone - which had never had the App before.
Having logged in for the first time on the settings screen, moving to the forum for the first time resulted in a message flashing past saying ‘you have been logged out’.
Nevertheless you are in a state where you can post and says you are logged in on the settings page …but doesn’t have your logged image/ button, allowing you to see DMs or notifications.
Have you had any luck looking into it?
