Encountered same issue here. Last night gallery icon missing so can't do anything recording/Learning of IR or RF. Today worse, can't even remove or add. Did you see any icons if you learn and add a button?
I can see the icon. But can't add or delete device at all, also tried delete one of the home but can't too.
I had tried roll back IHC apps version on the android phone and no luck as well. highly suspect is their server issue?
Anyone else having same error like the 2 of us here?
Thanks.
