Good but lags badly sometimes

This app gets so laggy it sucks, it’s a great app but it lags sometimes and those lags suck and last long

Not a horrible app

This app isn't horrible; it's quite convenient with its short videos and direct questions. But, as a student I do have a problem. In one of my world history lessons, I need to submit Mesopotamia, but the app flags it as a “possible spelling mistake,” and I want to submit it so I can move on to my next lesson.

The new update sucks

Before the update it was really good and i could actually go back and catch up on lessons i messed on the past day(s) now it wont let me- and for people that cant see or read properly because of sight problems or like me who has dyslexia i cant always read right, thats why Read Out Loud should be there always for you to have- and the AI??? Why use AI when it was fine before it?- it was way better before the update and Acellus should really go back to how they had it in like 2021

Terrible

This program is SO laggy. I always have to wait like 5 minutes for the app to open. The help videos don’t even help! The only class I actually learn are ASL and social studies when I had it. I really hope you fix this program
