I have upgraded all EX-Series at the customer to TC7.1.1.
Now, by chance, I've noticed that some of them didn't upgrade the Touch, sitll running on TC7.0.2.
Anyone an idea?
If the reboot does not help you can do a factory defaults on the Touch Panel
A reboot should trigger the upgrade on the touch connected to the codecs. Have you checked that the codecs for those 10 have actually upgraded to TC7.1.1?
