"Cannot Continue Download" when opening BIMx

[Geof Gainer]

I've all of a sudden gotten this message on both my iPad and iPhone when opening BIMx:

"Cannot Continue Download. 'Smith Residence' couldn't be downloaded because your device is not connected to the Internet. Please check and restore your connection in order to resume download"

... followed by the options "Resume download" and "Cancel download". My connection is fine with all other apps. Clicking "Resume" leads me to:

"Password Protected Project Documentation. Your password was incorrect..." even though all my models on BIMx Model Transfer are set to Public visibility.

These windows pop up for all my downloaded models one right after the other.

Any ideas?
