Or it could just be because you bought a paid version - it would be really shitty of them to ad advertising to your paid version, too. Likely many users won't (buy the Pro) and Tapatalk is taking full advantage of spamming forums without their consent and making money off of them without any kind of payout. Pretty crappy.

For Android users who want a good experience, I'd recommend RSBrowser - it's basically Chrome light - runs on a lot fewer resources and the formatting on SLi (as well as other webpages) looks great and is very navigable.
