When I tether my phone's internet connection to another phone, that phone frequently encounters the message 'YouTube is not available in your region' while trying to use YouTube. This issue occurred when I was with Fido and persists now with Koodo, suggesting a potential restriction imposed by Canadian mobile carriers.

Furthermore, I've noticed that when I check 'my IP address' on the tethered phone, it displays a different location than my actual location.

This issue does not arise when I'm in the US and use a prepaid SIM card or an eSIM from a different mobile carrier. Also when I was in my home country and shared mobile internet with a local provided worked without problems. This reinforces my belief that it's likely a restriction imposed by Canadian mobile carriers.

Is not an issue with YouTube or the configuration of the phone.
