It’s slow all the time (like it doesn’t clear up at certain times of the day), but it’s the longest for me when you hit the top tab buttons (like the scheduler or the daily plan). It takes about 20 – 30 seconds to load when you have to switch from one tab to the other.
And when you switch from family work to a student, or from one student to another, it takes about 10 esconds to load, and it will have the “one moment” with the spinning circle thing next to it.
And when you try to mark something “worked on” or finished, you get the “one moment” with the spinning circle, and it takes maybe 5 seconds for it to register. But as it is processing it, you can still scroll down and up on the daily plan to figure out what else you need to check off.
Hope that helped.
