This was their response about the tournament in my other post.
Heya, just to clear this up and confirm - yes, the new Tournament Mode is only available in select regions at launch (similar to Battle Pass Subscriptions). Our teams likes to perform tests like this to help gather live data and adjust those features before they open it up to all players in all regions.
The intent for any feature under testing is to use the data gathered to improve it and make it as best as we can before we launch it everywhere. With that said, this mode is launching in most regions and most players should be able to access it. We'll be adding more over-time and we'll make sure to note once it is available everywhere.
Thanks for sharing that! 
But my friend lives just beside me and he doesn't have any battle pass + he started playing almost a month ago then too he also has the option So why not i
If you are both in the same region then that might be a bug or one of you is using an account that was setup for a different region. For example, if you live in Germany but you used a VPN to create your account in Canada and Canada isn't part of this first Tournament Mode launch then you'll have to wait until it hits that region too.
İkr, confused af
Hey, is this in relation to the "Please Select the Combat Zone" and it told you that your region was Asia despite it originally be in EU? Did you happen to be on a VPN and set to that region, so it was detecting you there? Unclear if we can change or adjust that, but we'll check in with the team and get some details.
I even have a screenshot of it showing EU in the chosing screen, if you want to see
Thanks for explaining and that's very odd. We are checking into that to see if that's something we can manually change on our end or if this pre-selection (before it even starts) will matter.
We both live in India (same region) and we doesn't use any kind of VPN then too my friend has the tab but i don't have please have a look From Asia region
Ah, well we checked into this more and we were wrong about it being region based. It is more account based with a small percentage of players not getting access to it at launch. You unfortunately are likely just part of that small group of players. Apologies!
