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

Hi,
i got the same “system error”. Did you managed to upload the .aab file?
Galaxy Store only distributes the APK file upload that. You can build either one with WFS.
In addition if you are uploading a watch face app you must select China as the only site and that you do not use Google Mobile Services
