IOS Remote App no longer working on Kodi

Hi,

Just found this forum and I’m hoping someone can help me. I have Kodi installed on a FireStick and usually use the remote app on my iphone as I can never find the proper remote!
Yesterday when trying to use it, i started getting voice prompts and the menu system wouldn’t let me launch Kodi at all. I tried a few times, re-started the Fire stick but no success – has there been an update which has changed the remote function or is there a setting I need to change?

Thanks in advance
