user_on_another_team but account doesn't exist

Hi All,

Hopefully a quick one.

Background: Doing user provisioning testing on a trial team dropbox. It's expired, which I fear may be the problem here.

I'm getting the above error 'user_on_another_team' back from the teams api (/2/team/members/add) when trying to add some test users. I'm sure my test users don't exist because I'm testing with fake names with some numbers.

Would the trial instance being in an 'expired' state cause the above message to return?

Worth mentioning:

I can list the current users fine, just can't seem to add.

I've tried with an access token taken from the console, and also used the full authorization code flow to get the access token - same result.

Also, while I'm here, will an access token manually taken from the developer console work the same for the prupose of the teams API's (the user/group/role management stuff, basically)?

Any help appreciated.

Thanks!
