Remote Test Lab not showing uploaded app

Hi, I’m new using Remote Test Lab and having an issue with it: after uploading the apk file of an app to test, it is not showing in the app list. I mean, the apk apparently is uploaded because I can see the progress bar, but after that it’s not appearing anywhere. Any ideas?

Edit: I am also wondering, is it allowed to upload and install apps in Remote Test Labs, not developed with Samsung SDK?

Same problem. I’m very surprised that nobody responded to this as I’ve now had Unity generated apks upload, install, and never show up on two different Galaxy S10 Ultra tablets (currently SM-X920)
