Starting yesterday with the release of iOS 17 Release Candidate, the currently the available version of Tagify will crash on launch.
Again, Tagify currently does not work on the iOS 17 RC released yesterday (9/12/23).
It is highly recommended to avoid upgrading if possible until after the issue can be isolated and a fix approved by the App Store. The previous eight versions of the iOS 17 beta worked perfectly fine until the RC released yesterday.
My deep apologies for this issue and I will update progress as it happens here.
