Hi,

During the learing of Level3 - Advanced Training, in part Assignment no. 1, I uploaded a test file which was not suitable for the accepted format. Now, I could not remove it and could not unlock th next content. As shown below, I need to remove the “test1” file. I have waited for the evaluation few days.

Please advice how to reset the file?
