Alas, the tips on this thread don't work anymore, at least for me. "Whos' watching?" is back every day after a Prime Video update - even if you don't have a kids profile and have only one profile. Anyone with any fresh tips on how to remove please chime in, thx.
The channels on Roku are developed and maintained by the channel developer themselves. We suggest reaching out to Amazon's customer support team to see if they have any additional settings or options within their app that may resolve the issue you're experiencing.
