After disabling automatic Vercel deployments with Ignored Build Step setting, Vercel Preview Comments status check stopped refreshing in Bitbucket. Are Preview Comments only available using Vercel CD? I followed this setup for Bitbucket Pipelines.
The odd part is that on initial push to repository Preview Status is once checked.
Hey . If you're asking about the deployment link comments added to pull requests by Vercel's BItbucket integration, then yes disabling automatic deployments would also disable those comments.
I believe you could set up your Bitbucket Pipeline to add a comment with the deployment link if that's the only feature you're missing.
Hey , was talking about feature of Vercel Toolbar.
This status check is only updating after every new push to the repository.
I see what you mean now. 
I'll pass this along to the team to investigate. Thanks for reporting it!
