I have an issue whereby I am unable to recreate any groups (Add a Group) after a reset of the Device List.
I am running v1.02.05 build10.
I have tested on iPhone & iPad. Tried rebooting iphone, rebooting all discs
I have resolved this issue.
Both my ipad & iphone were set to use Apple iOS 12 as I am a Beta tester.
When I used an iPhone on iOS 11.4.1, I was able to use the app to create a group without issue.
Worth noting for when Apple roll out iOS 12 publicly in the next few weeks!
