Fix PowerApps Pipeline Deployment

I need an experienced Power Apps / Azure DevOps professional to jump on a remote session and diagnose why my Power Apps Pipelines are suddenly refusing to push the latest build from the Development to the QA environment.

Here’s the current situation
• Dev environment still runs perfectly, but when I promote the solution the QA copy stays on an older build or throws intermittent network-related connection errors.
• Only minor tweaks were made in Dev before this started.
• The pieces that consistently fail to update are the data sources and several custom functions; UI elements seem to carry over just fine.

What I’m looking for in the next three hours (budget capped at about $100):
1. Review pipeline configuration, environment variables, and any ALM settings that could be blocking the transfer.
2. Pinpoint and resolve the network connectivity issue behind the failed promotion.
3. Verify that data sources and custom functions deploy cleanly to QA.
4. Leave me with a short rundown of what was fixed so I can repeat the process with confidence.

If you’ve already wrangled Power Apps Pipelines and understand how authentication policies, service connections, and solution layers interact, I’d love your help. I’m ready to start as soon as you are.
