Wemo with Alexa

[Pat <forums@xxxxxxxxxxxxxxxx>]

I haven't seen much activity in this group for a long time.  Where did
everyone go?  I switched from X-10 to Wemo quite a while ago.  My
basic issue is that the devices work well from the Wemo app, but are
no longer reliable when using Alexa.  They used to work perfectly, but
now they fail to respond about 75% of the time.  I'm guessing
something in my network (eg, router functionality) has changed to
cause the problems.  I see a lot of people making the same complaint
in many forums and groups, but I haven't seen any fixes that work for
me or explain the root cause.  I would love to find a group or forum
where experienced people are discussing this kind of issue.

Any ideas?
