Any time I restart OH it looks like the Amazon Echo Control stops working and the logs say I need to check my credentials and try log in… If I do that then it works till the next restart.
Is there anything that can be done to fix this?
I think you need to marry Alexa… But she’s a bit coy these days 
Not sure if this is related but this seems to be written to the log when I enter the credentials again and save.
