Unable to access store after attempting to download a marketing application. Message appears:
We were unable to authenticate you
Looks like something went wrong on our end. Operation engineers are aware of this problem and are working hard to get it solved. In the meantime, you can keep an eye on the status page for updates.
How do I contact Shopify Live support to have this fixed urgently?
8/21/2020 I am having the same problem. I can't log into my store. The message is
"We were unable to authenticate you." Help? How do I contact Shopify? I see that Shopify has not answered any of the posts on this issue.
I had the same problem so I contacted Shopify.
The solution is to delete your cookies and saved logins.
(I am using Chrome so maybe it's different between the browsers)
If this solution doesn't work contact Shopify support.
