File upload issues are commonly caused by one of the three scenarios:Size of file - we currently support individual files up to 512MB in size. One option is to compress larger files to bring it under 512MB in size.File type - we currently support PDF, MP4, MPV, GIF JPG, PNG and PSD files. Adblocker - If you have Adblocker installed and the file contains the words "Ad" - it will not upload. The solution is to either rename the file without those words or disable Adblocker during the upload process.
