[App] Blink

Error „cannot read property ‚name‘ of undefined“.

Sorry to get over again: it worked for a while, now I got some new Blink outdoor and the problem reappears: when trying to add them to Homey (V.7, Blink1.07) I get this message again: „cannot read property ‚name‘ of undefined“.
Even my Blink mini which was already incuded doesn´t show up. Login+pincode are ok.
Grateful for any suggestions!
