Verify Position-Problem with external Cameras in Mapillary

What's the problem?

My Mapillary app (iOS) crashes on my iPad (iPad Air 2) and on my iPhone (iPhone SE) every time I try to upload images from my external cameras. The app crashes in the process of verifying the position of a sequence.

At the moment I have about 15'000 images waiting for upload on two devices. I'm not motivated to take any further images because I cannot upload them.

done so far

• restarted app
• rebooted device
• tried with a second device
• contacted support (first time: August 2019)

Extracting data from the app with iMazing

With the help of iMazing I was able to extract all (?) data of the mapillary app from my iPhone (59 GB):

• images
• metadata

Folder structure of the mapillary app data:

• cameras
  • externalcamera1
    • history.json: pair_of(image_name, time_stamp)
  • externalcamera2
    • history.json: pair_of(image_name, time_stamp)
  • iphone
• local
  • featureFeed: ? (2MB) (Feb 19)
  • userFeed: ? (41 kB) (Oct 19)
  • userUploads: ? (31 MB) (June 19)
• mapillary
  • sequences
    • a folder for every sequence: all images and all thumbs

Wo stehe ich grade?

• in der Datei history.json finde ich zu jeder Bilddatei einen Zeitstempel. Nun suche ich noch die Verbindung zur Position.

Stand Mai 2020

Auch jetzt immer noch Abstürze beim Uploaden der Bilder. Darum am 17.05.2020 auf dem iPad die App komplett gelöscht und frisch installiert.
