So I need to get a quick answer on this to make a go/no-go decision. The shared database setup we have in place between api.backendless.com and droneup.backendless.com (out managed instance) seems like it works ok for connections to api.backendless.com, but there seems to be an issue with the user-token. The user tokens that were stored for the user do not work when used on droneup.backendless.com. If we cannot make this work this option will not work for us.
We have fixed this issue.
