Hi guys, I used dash.upload for upload a 1MB, 5BM, 10MB file and then visualized them as datatables. After I upload a new file, the webpage just went blank for ~20s-2 minute(depending on the file size) and then the table and other components show up. Does anyone got similar problems? Does anyone know what could the problem be? I don’t have this error with previous dash version.Thanks!
