Adding channel connector broken

Adding that I am having this issue. I also discovered that I can see connectors on a newer team, but not on most older teams. did a survey of various teams and concluded that teams with little previous traffic, regardless of age, public or private, can display connectors, but older teams with some decent traffic fail with the 'Something went wrong' error. Doesn't to matter how many channels the team has, just if there was at least one channel with hundreds of messages.

Anyone have luck fixing this? If I don't figure out something soon, it's going to have a significant on our workflow. We depend on the connectors to send targeted critical notifications.
