I have 3 roku 3's and one roku stick and since the update to 8.1.0 on July 17th, 2018, we can't keep the remotes connected. My phone app still works, but the 4 handheld remotes won't stay connected. I can reboot the units and then re-pair the remotes and they will work for a short period and then won't connect to the roku. I have reset the units, but still having problems. I know there is an issue with this update because my units were working fine and then after the update they are ALL giving me problems in exact same way. At times I do have issues with apps not loading and getting the black screen, but those are not consistent. Any ideas? How can I submit this to roku? And will that even help? Thanks!
