Thanks for checking bigjohn20081983 - doesn't seem to work on my devices though. I can pinch zoom 'here' in a web browser, so we know that works some places. Doesn't seem to work in the app... will poke more, maybe an app I'm running is interfering with that one for some reason.
And excuse me Mojo66, social grace was never my forte! I'm a stay at home father of a 2 year old these days and consider myself very lucky to be able to do so! Very new to cigars, but have been a (steady) pipe smoker for a few years. Thanks again to all for replies and the warm welcome!
