Now that I’ve very happily (Thank you, Omni!) upgraded to OF4, I do not want OF3 - on iOS.
But if I try to delete OF3 on my iPhone (admittedly an older model (8 Plus) running iOS 16.7.5), I get what I hope is a generic warning (?) that deleting OF3 from my App Library will also delete OF data:
All I can say is that I deleted OF 3 from my phone after I installed OF 4 on it, tested it for a while, and made sure it worked okay enough.
I believe your OF 3 instance on your phone syncs separately from your OF 4 even if on the same phone.
To check you can go to your registered devices and see if there is an OF 3 instance of syncing. I bet you there is. If so, this should indicate that deleting OF 3 from your device would be fine. If this doesn’t make sense, I’ll explain more in detail.
The note is about deleting the data on your device which relates to OF 3. The data still held by the device associated with OF 4 will not be deleted and neither will any data sync’d in the cloud.
Each day I discover something new about OF4. So glad I didn’t let myself be swayed by the negative reception it got in some quarters. It’s all better than ever.
BTW, do you by any chance know of a way to get a ‘Synch’ icon on the main screen of the iOS version, please; or is it still a case of swiping down to do so?
