Not only does the app not pick up the latest release, it doesn't install the one it does find.
It goes through the loop of showing
Update, when clicked, it shows Queued, then installing, then all apps installed then back to showing Update again.
This means you can't test private links because you can't be sure to get the latest version, or know which version you actually got, as the displayed may or correspond to the version installed.
Totally defective.
Please fix.
