After creating a remote gateway connection, I noticed that when setting up a remote tag provider, the Provider dropdown doesn't display any available providers. However, if I manually type in the provider name, the tags do successfully pull into the 8.3 gateway.
Is this a bug, or is there something I might be missing in the configuration?
Yes, it’s still open. Your best bet is to contact support, give them the ticket number in the title of the post, and have them open a support ticket. That way you can be notified when the ticket is done.
