I have pictures uploaded with a similar pattern as seen in the above links provided by doktorpixel14:
As you could see, it is jumping forth and back. And there should be a way - at least for the Mapillary-team, to correct the order of these pictures.
This was uploaded using the Android App version 3.89.
Given the fact that uploaded pictures are deleted from the mobile phone, the advice to delete the sequence and upload again does not seem to be feasible - and even when I drove the route again, there is no guarantee that it would be in the right order the next time.
Request that the mapillary team is looking more profoundly in these sequences and suggests correction, possibly figures out and communicates the root cause. Thanks!
I'd be happy to fix those sequences myself, given the availability of tools.
