I was receiving the prompt both on my laptop and my phone; I had answered 'maybe later' on the laptop, but then noticed the phone was prompting me separately.
Did some research, and it looks like this is geared more toward phones - they're like app-specific popups (or messages). I suppose an ad could be embedded within a popup, but for the most part, these are geared toward supplying info to the user.
(On edit:) I also noted just now from replying to another thread - the software now 'auto-italicizes'... I'll explain...for those of you who are familiar with my postings, you know I like to use the '*' character in front of / behind of words to add emphasis (netiquette issue; I try to avoid caps) .
Now, if I put those in, the software will automagically convert anything between the two asterisks to italicized text. Nice.
