All unfinished map downloads will auto-resume when the app is launched over an internet connection, unless Auto-resume has been turned off in the Gaia GPS settings. When that setting gets toggled off, map downloads can get resumed manually by following these instructions:
1. Tap "Resume Download" in the map download details screen.
- Note: leave the app in the foreground to complete the download.
Completed downloads no longer offer the Resume Download option.
