There is a hosted feature layer with 7559 points in AGOL. We created 1000 more and wanted to append them to the hosted feature layer. The schema was a perfect match as it was downloaded from the same feature layer that was to be updated.

When i applied the updates all previous points were deleted and i could see only the new ones.
Why could this happen?
Is there any way to retrieve the old points?
the Service URL is:
