Hi and thank you for your contribution!

Please note for the future: changesets should be local.

In your case: Upload changes in StreetComplete before switching a continent / country.

To avoid conflicts and as a courtesy to reviewers, it is recommended to:
• combine changes in a small geographical area (within a city, district or province)
• keep changes within the same country
• upload/save changes before moving on to map in a different area

Why? Have a look at the section
"Geographical size of changesets" on this wiki page:
https://wiki.openstreetmap.org/wiki/Changeset#Geographical_size_of_changesets

Thanks for considering, have a nice day and happy mapping!
