Again, the only way I can really help here is with a diagnostic report. Without that, my hands are tied.
I also quickly checked in with my colleagues from Support today. Your last ticket was closed because they didn’t receive any further response within seven days of their last message. The last message was about Homey Backup’s rather than Matter as far as I can see.
If you’ve made your decision and want to move on, that’s absolutely fine as well, and I’ll close this thread. But if you’d still like me or our Support team to look into this and figure out what’s going on, please give us the opportunity to do so by providing the diagnostic report.
