Update: I checked the images before upload, from the “Ready to upload” in the Mapillary app, and also the local album folder. Some sequences have one image not saved in the Mapillary app and only saved in the local folder, so when the sequence is uploaded one image is left out. I guess this might be a performance issue probably due to overheat (This previous issue).
Here I attach some screenshots for reference. Last screenshot is the result after the sequences uploaded to the server.
