Hubitat Hub Update 1.1.3.116 is out and includes a patch to the SharpTools Hubitat App which should resolve the issue some of you were seeing when authorizing a large number of devices.
If you had trouble authorizing devices before, install the 116 release, try the authorization again, and let me know how it worked for you.
Special thanks to @stephack (and of course the Hubitat team) for helping me narrow down the issue.
