I am trying to get tweets from the past year, but I am getting 0 observations. I thought it was because I had the basic Twitter account that only lets you search up to the past 7 days, but I confirmed my Twitter developer account is the Sandbox: Full Archive. I am very new to rtweet and the Twitter Developer pages are very hard to decipher. I saw something about a Bearer token – I'm not sure what that is, but that could be the issue here. Thanks!
