I have been roku customer for 4 yrs plus with over 12 of them spread over relatives houses.
I installed 4 ultras and 2 sticks about a month ago.
They will pair normally to the tv and control volume and power.
Then about 3 weeks ago, they would stop allowing volume to be adjusted and the on/off.
Normal commands to roku (channels controls etc) work correctly.
If you power of tv it will work for a min or 2 then stop....then 5mins later magically start working again.
I have gone into the secret menus and forced the codes for for same brand and those do not work..I have to use the default codes for it to work.
I enabled the CEC on one display and one of them did not even have it as a option. The tv's are all different, panasonic, LG and vizio.
I could see one doing it but all of them is crazy...I even powered down all rokus except one and issue still arises.
Yes I did a full reset on one and it still has same issue. I even did the force OTA update.
These are the 2pack costco rokus that have a ultra and stick.
