I'm experiencing an issue where my Railway project isn't detecting changes from GitHub pushes, even though the integration worked successfully once before. Deploys aren't triggering automatically, and manual deploys seem to pull old code. I'm using the paid version of Railway.

Here's what I've already checked and tried:

• GitHub has the correct Railway app settings authorized: Verified in GitHub Settings > Applications > Authorized GitHub Apps > Railway, with repository access granted to the specific repo.

• Railway has GitHub linked: Confirmed in Railway Dashboard > Account Settings > Integrations > GitHub - it's connected.

• I've tried disconnecting and reconnecting GitHub: Unlinked and re-linked the integration in Railway, approving all GitHub prompts, but no change.

• Project has the correct repo and branch: In the project settings, it's set to the right GitHub repo and branch (e.g., main).

• It worked once: The initial deploy triggered fine after linking, but subsequent pushes haven't worked since.

• I've tried "Wait for CI" both on and off: Toggled this in the service settings, but no change.

• I'm correctly pushing to the right branch in GitHub: Verified commits are going to the matched branch.

• I've tried many empty commits too: Pushed several test commits with no changes or minor ones - nothing triggers Railway to pick up the update from GitHub.

• On GitHub, it's showing the latest commit: The repo reflects all recent pushes correctly.

I've also cleared browser cache, tried incognito mode, and checked GitHub webhook deliveries (no obvious errors). Could you please investigate? Logs don't show specific errors beyond no new deploys.

Thanks for your help!
