Llp Registration No DMSID error

Users are encountering a persistent 'No DMSID for this particular record' error when attempting to register an LLP, particularly during the resubmission of the FiLLiP form. Several users have reported similar issues with downloading the correct forms, often only receiving Form 9. Solutions that have been suggested or found to work include repeatedly trying to download the form, renaming attachments to be under 10 characters, clearing cache and cookies, and crucially, using the Microsoft Edge browser for all MCA functions.
