Ok, how does one remove extra user entries in the DJI go 4 app?  I have a total of 4 but only have one MPP.

tried a few things buit no joy yet.

The short answer: you can’t. I have the same problem and opened a case with DJI. They told it cannot be done.
You will notice that one of the users is the sum of the other ones.

I was afraid of that.   Thanks for the confirm though.  

I am sorry to tell it can't be deleted at this moment. However, if it is possible, you can provide me with the screenshots of profiles that were generated on the flight records, tell the DJI GO 4 app version, PM me your drone's serial number and your DJI account, I would like to forward to the engineers to check again. Thank you in advance.

So do we have a fix? I have 3 users in mine I'd like to combine them to one for everything including my dji.com account

Hi Straker, may I know if you need to gather the flight records on different drones into one page? Sorry to tell that it is not supported.
There will be at least 2 pages on the flight record column, the first page is the account info, the other is the specific flight record of one drone. If you had multiple drones, there will be different pages for each drone. If you don't need the extra drone (user's name), you can delete the flight records under this drone and sync the records again, please kindly note that the records will also be deleted. You may need to consider if you need that records before doing it.
Please let me know if I misunderstand the case. Thank you.
