It seems like generic limitation put on all data imports into Bubble. I faced similar limitation when getting data via API - 100 records on Personal plan. If you want to get more records you have to implement iterative workflow and repeat data importing step. I didn’t played with this workaround, but if it is possible to specify in the request from which record to start and how many to import, this approach could feasible.
