To get the most accurate solution, you should escalate the problem to API experts who deal directly with Power Platform integrations.

Gather Issue Details

Document all relevant information about your issue, including the specific file types affected (such as newer Word and PDF files) and whether the issue happens across all devices or specific apps.

No. The issue generally lies within the Power Apps integration and API handling mechanisms rather than standard SharePoint document library configurations.
