OmeTV Accept/Reject Buttons Not Working on iPhone for Two Weeks

For approximately two weeks, the "reject / accept" buttons in the OmeTV app on my iPhone have stopped working. When I tap these buttons while trying to start a live chat, nothing happens — meaning I am completely unable to connect with anyone.
I made no changes to any settings on my phone or in the app, and no updates were installed around the time the problem started — it simply appeared on its own. This issue makes the app entirely unusable.
I am requesting that OmeTV identify and fix this bug affecting iPhone devices as soon as possible so that the app can be used normally again.
