Welcome and thank you for posting here in the Roku Community, Mexico24!
It is highly appreciated that you've reached out to us for support and we'd be more than happy to be of assistance in utilizing the Guest Mode through your Roku account.
Before we proceed, may we first know if you're using your own Roku player or if is it the player that comes with the TV on your Airbnb unit?
Also, since you've mentioned that the error message you've been receiving is related to being unable to sign into Guest Mode, kindly open our Support article on How to use Guest Mode on a Roku streaming device to help you utilize this feature successfully.
Please let us know how it goes and we'll continue assisting you from there. Hope this helps!
Best regards,
Carly
Hola
I have read that article and it sadly it was no help. It is actually a TCL Roku TV in this Airbnb. Not a device. THERE ARE TWO TCL Roku TVs here.
