Field Maps 23.1.0 on iOS
We've had our field crews complaining that searching by asset number (format: A123456) is returning results in Antarctica.
Rudimentary testing shows that any length number, prefixed by A (or B, but not C, D et al) will return these 'coordinate' results. The correct, exact match search result appears below these results.

Is this something I've done in the search or geocoder settings, or a feature of a recent Field Maps version?
We're also experiencing BUG-000149944 from https://community.esri.com/t5/arcgis-field-maps-questions/highlight-selected-feature-and-zoom-in-fro...
So I'm thinking there were a few breaking changes at least to the iOS app.
Logging a support case now, but adding details here in case others are experiencing the same - or for you to confirm this happens for you!
