Hi trimarin,

You can upload your changes separately in Osmand.
Please use this feature to avoid huge bounding boxes as in this changeset. 

 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!
