Is your feature request related to a problem? Please describe.
Currently, when there is no connection to the Internet or Nostr Relays, location data is not stored or transmitted. That is, even if the location is successfully determined, the movement track will have a gap after the connection appears. Visually, this looks like long straight sections of the track that do not reflect the trajectory of movement.

Describe the solution you'd like
I suggest that the application record all the points, regardless of the success of the attempt to transfer them via "Share". When access to Nostr Relays appears, transfer not only the current location, but also all the data accumulated during the offline time.
