Data in Table/Layers disappearing

[BlakeMorrison]

Yesterday, I created a table in Pro, added records, and 30min later came back to an empty table when I wanted to upload it to AGOL.

I also added ~2000 features to an empty layer already hosted for a couple weeks. Today that feature service is empty. My Field domain edits all remain in place.

Anyone else having these types of issues?

Sounds like you're also having this issue in Pro. Could it be someone else did this? Are you the only one that can edit that layer/database? The only one that can connect? How did you add features to the layer already in AGOL? Directly? Append?

I was editing the layers via Pro at the time - same session - unsaved messy temp situation. I'm the only one with access to the layers/editing. I was willing to believe I was confused or mistaken the first time it happened, but the second time I didn't imagine.

How did I add features? Copy-paste from another AGOL layer, within Pro. Hit save. Edit Web map for a day in Map Viewer. Build out symbology, popups and forms in Map Viewer and test them all. Duplicated the layer and symbolised it in a different way.....

Next day: "oh look, 2400 records are gone. But all my symbology is still setup in Map Viewer."

I've talked to tech support. They haven't heard of any similar issues. I've half decided I must have got unlucky with a buggy/corrupt session or something like that.
