That's interesting. I just went to check that out and I see what you mean.
Of the 10 entries showing as 'My Tournaments' it seems like a very patchy list with one going back to December 2019, and the vast majority of the more recent ones I've entered and played not listed at all.
And when I click on 'Enter New Private Tournament' it asks for a tournament code.....
Like I said, interesting.
