Who I have the same questioned this topic

Really need to get Message+ app for my Windows 7 desktop while working. Go figure they only have app for Windows 10.  I looked it up and 48% of windows pc's are using windows 7 - why would Verizon not accommodate us?  It can't be that much of a leap to have it work with Win7.  Very frustrating.

Not sure if anyone from Verizon checks this - but if they do, please help!!!!
