We are having issues with uploading files with .docx and .xlsx extensions even though these are included in the list of allowed file extensions in the Files App settings.
Any assistance in resolving this would be greatly appreciated.
Screenshots to this effect are as follows:
(Studio > Settings > Files)
(6 files attempting to be uploaded)
(4 files successfully accepted with error message given for the other 2 - .docx and .xlsx files)
Many thanks.
