I and not only me, more people have got this same issue in their games 2 days ago again and Roblox immediately resolved it upon couple of user reports
Here it happens again or something similar to it and would like to see if anybody else got it as well
“DataStoreService: AccessForbidden: Access forbidden. API:”
Update:
It stopped spamming as of for now but i am willing to keep this report open in case it is an issue to be fixed and prevent it to happen again
