Roon IOS Controller APP not working

Tonight all of sudden my IOS App stopped working on 2 of our iPhones. It tells me we need a software update. BUT when I try and update on iPhone it does not show any update available. It also shows that my Core is is 1.7 and when i go in Core on computer it tells me I am up to date! What is happening and how can i fix it?

A post was merged into an existing topic: Where is 1.7 for iOS? [Update will be available soon]
