Rhythm Festival - Initial Loading Screen - Transmitting Freeze?

I just updated the game after not updating it/opening it for a year. The initial loading screen right after updating was "transmitting" but froze up 10 seconds in. I went to home menu, went back in, and that got it unstuck. It loaded 5 seconds later and loading screens have been fast since then. Should I be worried about this? I hear that stuff like this happens when the game has trouble connecting to the internet. But at the same time, I also heard that this game just has a ton of bugs and that this happens from time to time. Drum n Fun earlier took a solid 30 seconds on the Switch logo/licensed by Nintendo screen, but that could be just because I have a ton of songs.

Been having internet issues recently so I wanted to make sure it isn't a me problem.
