How do I connect integrate Trello with a salesforce sandbox.

[Muyiwa Opeola]

I tried to integrate Trello with a sandbox and it seems to connect. I was unable to attach opportunity. 
I tried to disconnect from salesforce so I could try again, I could see only 2 options: "View Power-up" and "Disable".

I tried to Disable and enable again, but there was no option to link to salesforce anymore.

Hey Muyiwa, 

Maybe this problem is related to the fact you're connecting Trello with Salesforce sandbox. I didn't see a report about users facing a problem with Salesforce in production.

Could you raise a ticket (www.trello.com/contact)? We'll be happy to check this case with you.

@Muyiwa Opeola Are you able to connect your Salesforce sandbox to 'attach opportunity' (using Salesforce Power-up) with Trello card?
