I own the retail standalone version of Lightroom for PC. I have no intention of using Lightroom Mobile. Regardless, on startup I get regularly harassed by Lightroom to sign in to Lightroom Mobile...only to then be able to tell it to pause sync. This is frustrating and annoying...can your software not offer an option to just indicate "nope, I don't care about Lightroom Mobile" and be done with it, making it opt-in rather than constantly having to sign in? It feels like a money grab/upsell every time I fire up Lightroom to get some actual work done.
