Illustrator on the web (beta) is unable to recognize any changes made to the document

Hello! I've been noticing with the Illustrator Ai beta that in the last day or so it just stops recognizing the changes I'm making. I log in, it seems like everything works fine and then shortly after I try to make a change and nothing happens on screen. I can keep clicking on things and it acts like it's doing it but i'm unable to see anything actually change. and then if i refresh the page and try again nothing has been changed. not sure what is going on but would appreciate if I could get this to work consistently, thank you!
