Power BI Web - SQL Table Row Limit?

I'm doing some testing with getting the refresh function to work in the web app. I have 3 dashboards each connecting to SQL server tables:

Dashboard 1 - Data table has 27 million rows (550mb file)

Dashboard 2 - Data table has 1.5 million rows (43mb file)

Dashboard 3 - Data table has 600k rows (25mb file)

Dashboards 1 & 2 refresh just fine in the desktop client, but will not in the web app. Meanwhile, dashboard 3 updates just fine in desktop and web. That said, is there a limit to the number of rows in the SQL table that can be imported to the web app?

Thanks!
