Problems with Nintendo Dogs on cats?

I have a problem with my Nintendo Switch lite dogs and cats, I have had it since c. A. 5 hours and got to level 10. At the bottom right there are always hearts that, when you have them full, the level increases. Now I don't get to level 11. No matter what I do the heart does not fill up. I restarted it, deleted it, pushed it in and out, but the problem remains.

I think you can only do 10 levels a day
