I recently noticed that if you try and connect any of the tinxy products to a WiFi 6 router , it fails.
But if you connect to a particular SSID and then use the same SSID and password on a WiFi 6 router then all the devices seem to connect to it without any trouble.
It’s only when you go with a fresh start you get problems.
I tried with TP-Link Archer AX-72
strangely enough the problem sometimes can also be seen with some other routers too, like today itself i faced the same issue with TP-Link AC1200 (C50).
