(This issue is also posted in KartaView GitHub issues here. Sorry if this issue is unrelated.)
A while ago when checking on my KartaView profile and I saw the function to link to Mapillary account, so I decided to give it a try. I have recorded some tracks using the KartaView app, after uploading it, it takes a day or two to show up on Mapillary. And I saw that in Mapillary, some tracks are duplicated twice or even more than twice, it can be up to five times. I hope someone could fix this problem. Thanks.
