This isnt really a solid solution but what i did after much deliberation was set up a complete new user business account (paid for a new user) and share everything over, make myself admin and share edit/invite access after identifying that it worked on another work colleagues account.
Its most likely a very rare issue so i thought to save everyone the trouble (both myself and technical staff) I would bite the bullet and do it.
I think it might solve an ongoing issue i have had with my account and syncing also, so probably worked out for the best
