Problems with unlocking gen2 ebikes when no non-ebikes at station?

I'm experiencing an issue and would like to know if others are as well. Since an app update a few days ago, when I try to use the bay wheels app to scan the QR code, as normal the dialog to select either full or weak power pops up. However, when I make a selection and click OK (as I typically do), the dialog closes but there is not even an attempt on the dock to unlock the bike, nor any indication in the app of something in progress or a failure to unlock. This has happened at multiple different docks.
