Update: Now the install is working quickly (with last build). Not sure what changed.
Are you using hydration?
No. Build is not all that bad and neither is download and install vs the overall time to get an app competed.
To put things in perspective, just testing on 5 device (android phone & tablet, iPhone, iPod, iPad) takes so much time that the build is no big deal.
I just thought something was wrong because a new cli was being used today and the first build I do has a problem after the ipa is installing.
Maybe record a video and post it so that I can see exactly what you're talking about? Be sure to cut/black-out anything sensitive.
