I have bought a bunch of books since launch... I just now bought the Legendary Bundle and from what I was gathering is... that this was part of the bundle. I have even looked it up online and it always says it is part of the bundle. Why am I not getting it. Same goes for a few of the adventure books. I thought the bundle would give you everything for that kind of money lol. Can some one please let me know if I just having issues or if it does not come with the bundle. 

My understanding is that yes it should be (cant confirm i bought the bundle before it came out) I expect someone official might see this faster if you post in the support forum. Do you know which adventure books you're not seeing? I know tales of the Yawning portal is like 7 of them under one heading.

I'm pretty sure everything except the map pack is in legendary bundle.

There could just be some delay in gaining access after your purchase. Try this link (https://www.dndbeyond.com/sources/ggtr). If you still don't have access after this long, contact support (https://dndbeyond.zendesk.com/hc/en-us/requests/new?ticket_form_id=602788).

The 2 waterdeep adventures are the one I can not get. I bought the bundle about 2 weeks ago and still can not get Ravnica. Sadly Ravnica was what I was mostly wanting and I was sure it said it was part of it. I only needed that for the source books and about 5 adventure books. 

Yeah, definitely reach out to support, good luck!
