I have been using the exemption for the last year and it wasn't an issue until now. Not that I've encountered anything about it, but it's been noted on the apps (Uber/Lyft) that they want a Business License. Uber accepted the Exemption on my second upload attempt and Lyft denied my initial attempt at it. I just signed up for Lyft. Why wouldn't driving for either of these companies be considered a "home-based" business? You are technically operating out of your own home (unless you decided to rent some building/garage to park your car). You also don't report to any particular location to "start working".
