Hi @Anonymous,
I think Power BI Data refresh should be the issue.
By default, Power BI refresh the package files stored under OneDrive hourly:
"
For files loaded from OneDrive, automatic refresh occurs about every hour for data that does not come from an external data source.
"
For tile refresh, it happens about every fifteen minutes. Tile refresh updates the cache for tile visuals, on the dashboard, once data changes.
For more information, check:
Data refresh in Power BI
For PowerApps, it updates the data in real time.
Regards,
Michael
