According to one of Samsung Canada's Managers @Steve01, said essentially that Samsung Canada's Support isn't capable of providing support for the Betas.
I believe him.
I always just Flash the US Betas myself, but have you read the responses from Samsung Moderators & read the "happy" Samsung Canada Support Chat reviews lol.
If people have the chance to get the Betas as OTAs, there's gonna be a lot more work for Samsung Support & they are largely incompetent, when it comes to even the simplest of questions.
People would still install the Betas & most don't understand why they are even called Betas.
