The iphone where it’s not working is on the latest IOS 16.7. I have the latest Koala … at least, App store can’t offer me an update on what I have (1.4078 (5887))
I have it working on two old (probably +6 years) devices, running IOS 15, and Koala 1.4080 (5901) …
That’s interesting … must be the version on the app store for my new phone has not yet updated.
EDIT: Aha, problem sorted. I ‘offloaded’ the app then re-installed. Now I have koala 1.4080 and the mixer. Thanks for the prodding about versions, should have thought of that myself
