A user is trying to install my watch app via TestFlight and getting an error message that the watch app needs to be updated when it doesn't.
This seems to be part of a bigger problem because he is one of two users in Switzerland who cannot install the watch app when downloaded from the App Store. No-one else worldwide has the problem so it seems a Swiss App Store issue, which is why I suggested he try using the beta. This didn't work so I suggested an earlier beta and this didn't work either (same error), so it is not related to the binary.
I have tried contacting Apple Support for the App Store but they helpfully said they would get back to me in 2 business days (i.e. 4 days time), which isn't much help because I have already had a one star review on the App Store as a result of the problem.
So I thought I would try the TestFlight angle. Does anyone know why it would say that the watch app needs updating when it doesn't?
Also does anyone know how to contact Apple support quickly? I can't believe that the earliest they can get back to me for a production issue is 4 days time!
