Domo performance

Has anyone else noticed that lately Domo is incredibly slow? I've been trying to reduce dataset size, but even editing cards, it takes 30 seconds to 1 minute just to open the analyzer. I've also noticed that data sometimes doesn't change when I edit the card, but when I save, close, and reopen, then the data changes. Also when editing dataflows, it takes forever for the magic etl tiles to load and change the tile joins from dashed line to solid line. And sometimes making changes in the tiles doesn't get recognized at first and it looks like there is still an error on the tile when really there isn't. Just some really buggy stuff been going on. Anyone else having these issues? It seems like there was a huge code change after the last release or something.
