iOS App issue

Over the last few days I’ve been unable to respond to Support Tickets in the iOS App.

I can attempt to compose a reply but can’t see what I’ve typed (the keyboard does appear) and there is no option send anything.

This was on iOS 18.6 and have since updated to 26.1 - same issue.

Being able to respond to tickets while out the office is important.

Anyone else with the same issue ?
