Alexa-remote2 not supplying all requests reliably and other issues with it

And tonight's continuning saga is that Alexa has stopped speaking when I send custom commands to the Alexa Routine node :frowning:

Not changed anything (honest) and all working last night when I used it for my door locking stuff - tonight neither my main LivingRoom Dot nor my working android phone will speak :frowning:
Object looks fine (same as yesterday) - node reports sucess - just no sound comes out at all :frowning:

I'm not very lucky with this set of nodes.....
