[BUG-000147089 Snapping stops working after using the Edit Vertices or Move tool with a specific workflow]
More info: Snapping can temporarily stop working for the Edit Vertices or Move tools if an edit is finished by activating another tool like the Select tool instead of using F2 or by clicking the finish button on the edit toolbar.
This bug will be fixed in the next version of ArcGIS Pro (3.0) Until then, to avoid the issue, be sure to finish edits using any of the following methods:

- Hitting F2 on the keyboard
- Clicking off the edited feature (somewhere else on the map)
If it should happen, to get snapping back, click on the Active Select tool on the Modify Features pane:
