Hi John, that is exactly the problem: that pop-up window does not show up. I wish it did.
I now checked all three licensed features:
– Roadbook demo mode, pressing buy plugin: nothing happens
– OBD2 demo mode, pressing buy plugin: nothing happens
– Map demo mode, pressing buy plugin: window opens with “Select subscription duration”. When selecting 12 or 6 months, the same happens as if pressing “cancel”. It returns to the previous “buy plugin” screen.
