Hi Patcach-be,

Welcome to OSM and thanks for contributing :-) 

One general recommendation: changesets should be local.

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

Please note that it is considered polite to at least briefly reply to comments on ones own changesets.

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

Please also have a look at this page as you use StreetComplete:
