My organization has been extremely frustrated with this issue. We often need to overwrite feature layers on AGOL, but have been experiencing a situation where the overwrite initiated in Pro goes through without an issue, but upon viewing the updated layer in AGOL, all the features have been removed. Publishing new layers works fine, but overwriting an existing layer removes all features and results in an empty feature layer, when the original layer in Pro has features.

Field and symbology changes are correctly inherited into web maps containing the layer, but all actual features are gone. Has anyone experienced this or found a solution or explanation?
