I use the PA apps FireBird(FB) and FileZilla(FZ) mostly, and a few other PAs.
I knew the FB and FZ were a bit behind, and wanted to use the PA platform software / manager to mange updates.
But any time I asked it to check if any apps needed updates, always reported that they were all up to date.
My FB PA was at 17.x , the latest release was 24.x ,,, (didn't realize my FB PA was that far behind).
My FZ PS was 3.7.1, latest 3.7.3 ,,,
I don't have the automatic update checker turned on..
just leave it me to manually use the update checker utility / function built into the PA Platform app.
