having issues with new Pro firmware, (its just come back from a service.... 1, the app fails to connect. always, have tried deleting app and re-installing. it also works fine still to connect to MiMIC and XL. so i know it works there. 2. the pro will boot up and at some unknown point for no rhyme or reason will go limp and all buttons will lock out. only way to sort is remove batteries to turn it off and start over. any idea whats happening? I use a lot of Blackjack stuff, find the stable firware doesn’t cut it. may have to use it on next job though. would roll back if i could to previous Blackjack firmware. thanks Rob
