We are not aware of any current iOS-specific issues.
Older devices running iOS 12.5.5 previously did not work with AC Central 3.x. This was fixed with the AC Central 22.214.171.124 update released Jan 3, 2022.
The iOS 15.1.1 update broke sermon downloading. After that update, sermons will not download correctly or plan. Sermons downloaded prior to the 15.1.1 update will play normally. FIXED - the iOS 15.2 update fixed this problem.
