Hello @MaryGraceMcClellan,
I'm not aware of any size limitations for Experience Builder. This could be very different per Enterprise deployment.
Depending on your Enterprise architecture, version, RAM, Cores, Space, etc.
Here are some troubleshooting things you can try:
- Does the issue appear in ArcGIS Online?
- Add the service to AGOL and use the Experience Builder (if you're able to)
- Does this problem occur on a smaller dataset?
- If it does not occur, try adding datasets in increments
- To find out what the limit is
After performing these troubleshooting steps, I would suggest reaching out to your local Esri Support distributor. Our analysts can help determine if it is your architecture or if there is an issue with Experience Builder.
