I have 4 Roku TV’s and 1 Roku Ultra. 1 TV is on 14 and rest are on the 13. All Roku’s are fully updated, APP is updated, and Tablo is updated. Roku APP will not open. It blinks and goes back to the home screen. Out of the blue Roku APPs stopped working.
iPhone works, Onn 4k, and Onn Stick works. Thanks to @269587 , he sent me his Onn Devices to test with. They work great. My wife needed to watch her shows.
Confirmed solid wireless signal. Ultra is hardwired. I pump out about 10TB a month of data out of my home. My router/firewall has the horsepower. Removed all ACL’s and VLAN’s. No go.
Kind of a bug a boo that Roku’s are having issues and all of my mine are out too. But with a different behavior.
I do like these Onn devices though. The wifey may stick with them in the living room and the bedroom. Tablo APP loads so fast on it.
