Puzzle Rush High Scores seem to be Broken

The high scores in puzzle rush in the "all" don't seem to be working. My high score is 25 but on the leader boards of my friends it seems to be 20. As well, my friend's score is 26 but I remember it being 29. As well, half my friends seem to have been erased completely with no scores whatsoever. I think this may be something with old scores but my previous high score was 21 not 20. Is this just a bug for me? 

Here are some pictures of the bug:

Before you have a 25 high score and then you appear to have a 20 later on in the same minute. Question did you just get the score within fifteen minutes? If so, then the leaderboard doesn’t update for every 15 minutes. I know for a fact this happens.

It will appear to change it on your device but it won’t change the leaderboard till fifteen minutes have passed since the leaderboard updated before it

No, I got 25 about a week ago

Also, that does not explain half my friends (including you) not being in the leaderboard

I haven’t played puzzle rush at all so that’s why me.

That doesn’t make any sense

I know EarthRock1987 got 28 before as well

About 1-2 months ago I believe

And my highest was 29
