Hi @paul_k,
Just to say, there is a workaround for the app issue where you don’t have to fully remove the app. You can just go to iOS settings, go to storage, search for the relevant app and select to “Offload App”.
This uninstalls the app but keeps it registered on your device (so it is easier to reinstall).
After connecting successfully, simply press on the app and it will re-download from the App Store. Once re-installed, then open the app and you get straight back in without having to set it up again.
