Super Laggy

Just downloaded my BetterCampus today and am loving it! However, it’s super laggy. I like the idea of taking notes in Canvas, but it just straight up isn’t working. I created a note and it suddenly created a tab that said “older” and I couldn’t open the note until I refreshed the page and then it said “today”. I tried to delete the note and rather than deleting, it just started putting the number of notes for the course into the negatives.
