My plan is, first desktop, and when that works, mobile-on-desktop, 
followed by Android. But ... despite numerous
hours hacking around, implementing the exact steps from the TIO doc, no 
progress. Fully unclear at this point why
the notification and credits indication are not firing. So a bit stuck 
at this point, but still pretty sure that following
the TIO doc is the proper way on.
