When I bought my new device it set up under my @yahoo.com account. No code or option came up to link it to my account @Gmail.com or @yahoo.com. That is when I realized my son's Roku is on the account @Gmail.com. I want all 5 tv's on one account. This article and none of the other 5 I have read told me how to do.this. Roku has no support number to call this is ridiculous. Please help me.
I don't know if it's the only way, but one way to do it is to do a factory reset on the devices you want to transfer to the other account and then link them to the other account when you go through the setup. Just make sure you're logged into the right account at: https://my.roku.com/link
