Hi Sam,

This is to inform other community members about resolution.

After TeamViewer session we were able to resolve this issue. The issue occurred because of lookup list view threshold. There were too much lookup fields in the SharePoint list.

In the next version we will add error notification for browser console about the error with lookups threshold.
