VRM app not working on iPhone7 again

It’s happened again…but worse.

Yesterday for some unknown reason my VRM app and widget disappeared from my iPhone7. Today I re-installed the app but it fails to load anything. I just get the continuous spinning thing. VRM works fine on my Windows laptop and also works on the phone if I go in via VictronConnect.

I’ve done all the usual cache clearing, uninstalling turning off and on stuff but nothing makes it work.
Did something get updated again and broken again?

OK - that’s odd. I just turned the phone off and on again and suddenly the app started working again so ignore this topic!
