Hello.
Generally, in OSM whenever possible it's better to update the existing features into their current state rather than delete existing and create new. Doing that preserves history of that feature, which can be useful to refer to in the future.
In this edit it appears that for some reason you deleted the polygon for the Russian embassy and recreated it again.

Additionally, you created a closed way 1291940537, yet tagged it as a multipolygon.
And created relation 17710791 consisting of just a single member.
When making such edits, please check that you are accomplishing what you are trying to do...

Additionally, when mapping tennis courts, they should be mapped to the actual tennis court itself, not the surrounding area, which can be tagged separately.

I corrected these issues for you.👍
