I click on a link to a specific Sketch canvas.
Since I am not logged in, I am presented with the login form and proceed.
After this, I land on the Sketch home page of the project.
I have to click on the original link again to reach the intended page.
Hi there 
We have been testing this on our end, but haven’t been able to reproduce the issue. Perhaps we’re missing something.
Could you please share a screen recording of your steps to reproduce the issue? If you’d prefer not to attach it to this forum, feel free to send it via email to productsupport@sketch.com
Cheers
