Upload changes in a collection

[debuglevel]

Use case

After collecting a hundred quests in offline mode, I upload them at home and watch how each single change is uploaded. That's not really a big deal, but still seems a bit odd.

Proposed Solution

If there is an OSM endpoint to upload a collection of changes, upload all of them in a single request. If there is no such endpoint: just close this issue 😀

It is possible, this is how all other editors do it. However, it is not possible in StreetComplete. I explain how the upload works here, if you are interested:

(For uploading each individual change, the app first downloads the most current version of the element(s) it is going to change. This takes longer but makes conflict handling easier.)

I think the thing that bothers you the most is that all the quests on the map blink all the time during upload. This is an issue of the map rendering and cannot be fixed (without exchanging the map renderer, see #3123. What you can do, is just send the app into the background, it will continue to upload the changes.
However, currently it might be that after some time, the app will stop / cancel uploading further when it is in the background for too long. I didn't test it, but I think this may happen. However, this would be fixed as a side effect of fixing #2967 .

It was rather mere curiosity why they are not handled together. Thanks for the explanation! :-)

Ok, short answer: If the upload for one change fails due to a conflict, it doesn't matter for the rest.
