Sync devices is failing between devices on a previously working wifi network.
It is failing from Apple to Android, Android to Android, Android to Apple.
Apple software is V 1.732
Android is V 1.6.51
I took the 4 scoring devices home and added them to my home network, same problem.
The firmware at the range was updated just prior to the issue. My home firmware on my ASUS RTAC-88U was also recently updated on 12/11/20. (v2.208) No peer communication.
I moved the devices to an old network that has only TIVO devices and the Sync works properly.
It appears that the most recent firmware is disabling the peer to peer communication over the high ephemeral ports that the Practiscore app uses.
Any idea how to fix it or why it is happening? If this is the result of a security update that is hitting commercially available routers, this may become a larger issue quickly.
