The autocomplete polygon tool in ArcGIS Pro 2.3.0 sometimes does not work, or is unavailable from the create tools menu. The split polygon tool is also deleting my polygons. Has anyone else experienced something similar?
No. As for autocomplete, you have created at least one polygon before you try to use it? As for split you followed

Split a feature—ArcGIS Pro | ArcGIS Desktop
Yes, I have other polygons I'm trying to build off of. Sometimes even filling in gaps between other polygons isn't enough to get autocomplete to work. Autocomplete has consistently worked in the past, but not lately. For splits, yes, I am drawing a line across a polygon, starting and ending on the edges, but when I hit F2, the polygon goes away, and ArcGIS says the split was done successfully.
This is something that Esri Technical Support can help investigate. Are you able to create a case with Support? - https://support.esri.com/en/contact-tech-support
I've tried to reproduce the behavior you are reporting in 2.3, but so far, I can't. Does the Check Geometry geoprocessing tool report any issues? - Check Geometry—Data Management toolbox | ArcGIS Desktop
Does it occur with certain features or all features? What's the reproducible pattern?
