  shared from the Files app or iCloud Drive.

### 1.4.13 — 2026-05-25

• Fixed a crash when loading GeoTagged photos with missing or invalid GPS metadata.
• Fixed a crash when the GeoServer returned a non-standard JSON response for layer lists.
• Fixed an issue where alert dialogs were hidden behind the map view on certain screen sizes.
