Right now, spotlight mode is available when the host has a paid account, but not when the guest has a paid account.
This doesn't really make sense and is a needless roadblock to onboarding new users and getting them excited to drovio.
I have a paid account and I frequently encourage people to try out drovio and always recommend it for pairing. I should be able to use the spotlight as a paying guest whatever the billing settings of the host.
