Yesterday I could upload csv files (~2-5 MB) and was working on an analysis of the data. Today it can not access the data from yesterday or upload any files. I tried pasting chunks into the chat too and it can’t do anything with it either. Feels like I hit my memory allocation or something like that. totally stuck. 
I get this back:
It seems there’s an issue accessing the uploaded file directly. Could you re-upload it, or paste a small sample of the data here so I can structure and plot it accordingly?
