I'm trying to push and pull commits through SourceTree to the repository "crm-emails", associated with my organization, Betterment. Every time I try to push OR pull, I get the error "remote: Repository not found.
fatal: repository 'https://github.com/Betterment/crm-emails.git/' not found".

I had my IT team check my permissions and I have full write access to the repository. I contacted Github, who gave me supposed instructions, but did not solve my issue. I am still getting the same issue.

I have relevant screenshots I can send as well in order to figure out why this is happening. Other members of the Marketing "team" that this repository is associated with have push and pull privileges with the same settings as my account.

Any ideas?
