Hi BorisOkunskiy,
The files are checked by members of the Source team, they usually try to work on it once a week to make sure things are moving forward. The asset you uploaded should be checked soon!
We are also working on things to improve the approval process to make it faster.
Things that are checked are:
- does the asset work as expected
- are there IP issues (are there images or logos used which are copywrited)
