Hey @pedrolamas and @DVaughan, any idea why the build hasn't reported back? We can't merge until that process has been reported completed.

[pedrolamas]

No idea, I was thinking the same myself...

[DVaughan]

It appears that the pipeline was not triggered. I don't know why not. Perhaps make an update and see if it is triggered.

[pedrolamas]

@punker76 can you please force-push (or make any other change) to your branch so we can check if the build pipeline starts as expected? Thank you!

@pedrolamas @DVaughan @brianlagunas I pushed a minor change, but it seems like the build pipeline doesn't like this PR. I can close this and try to create a new branch and PR...

[brianlagunas]

@DVaughan @pedrolamas Looks like we have an issue with the build server. Who can look into that?

[DVaughan]

Currently looking into it.

[DVaughan]

@punker76 would you please try that again. I've switched to a GitHub action and it's waiting for status. But, I'm hoping it will trigger the action with another commit.

[DVaughan]

I've verified the build locally for this PR. I think the PR might need to be recreated for the action to trigger, so I'm merging without the status.
