TFT LP is not increasing...

So far, I won 4 rank tft games in a row and my lp and rank stayed the exact same. After winning 3 of those tft games, I decided to look at a league thread to see if anyone else was having the same issue. I noticed that someone else had the same issue, but their solution didn't work for me, which involved waiting so that the "skipping the stats" didn't appear. I completely understand that it's in beta, but it would be much appreciated if y'all can look into the issue.
