Namron devices fails after last upgrade to 2.2.92

After the last Namron app-upgrade to version 2.2.92 some of the switches are not working. I got totally 8 switches, 3 of them are now failing.

Anyone else with the same problem? And how can this be resolved without having to pair them again?

Did you PTP?

Yes, but probably not as long as it says in the PTP article. I’ll have to give it another try.

Same problem after PTP and waiting 40 minutes. The hard way then…
