Yes exactly that. If it's only available on Gold membership preview and not to Tinware +Plus subscribers that's what they should have said instead instead of annoying their customers.
Thanks for confirming that Malc. Everything else in the way of DLC is on offer to me in the Content Store app attached to my TRS22 install, - it's only the Tornado Pack that's missing.
It's definitely available to normal plus people as well as gold plus people. I downloaded it and don't have gold...
