Error uploading binary file

Hi everyone, I’m new to this and I need your help and thanks to anyone who can help me with the following: when I try to upload a file to the galaxy store with the name for example (mechanic.aab) , I can’t complete this upload because the following error message appears “system error!”… :disappointed:

As I wrote in the other thread, I can reproduce this. I have not gotten any response from the seller store yet.
