After the model is uploaded to the Matterport account it can be restored back to the device

The model may be retained on the device for further scanning.

The device may become full quite quickly

Jobs can be:

Transferred to another iPad using AirDrop

Downloaded and backed up

Deleted

A model may only be re-uploaded to the same system, either iOS or Android

Large file sizes require cloud storage, Dropbox, WeTransfer Pro, or similar

The best practice is to download models after uploading them to Matterport and store them securely, before deleting them from the iPad
