If you see this message: 
Something went wrong. Please try again. 

That means: 
The invitation was not delivered and the system cannot determine where the error occurred. 

What to do:
Try to send a new invitation by clicking the Invite button. If you get another "something went wrong..." error, further troubleshooting will be required, so please contact Streem support. You can always use the "Link & Code" invite method as a workaround.
