[2019] Thanks 343! Also quick beta question

So yesterday was my birthday (finally 18) and I was really hyped for the reach beta on Xbox, since I never got to play it online back in it's glory days. Now I was pretty bummed out when I didn't get a code yesterday but, then today I actually got one! Works out perfectly since i have a lot of free time today. But I'm wondering if you guys who already downloaded the beta could help me out? I already reinstalled Xbox insider and made sure I didn't have a previous mcc insider on my console. I also hard reset my Xbox. But when I try to download the mcc insider it's like an 80gb download and I can't check the version number to match it. I was wondering if any of you remember the download size or how to check for version number? Thanks a bunch

Edit: got a 5gb download now, that seems to be the right one. Thanks again for the help :)
