Can someone pls explain to me why updates after the market closes is gonna do shit? (Stockinvest website)

Stockinvest looks like an amazing website etc.. but how on earth is updating once a day after the market closes help??? Like for example something was last updated as a strong buy so the next day I bought it- then after the market closed and they finally update it again I see it changed to a strong sell- comes out I bought it at the time when it was a strong sell but I didn’t know cause it wasn’t updated 🤓 (“at that moment I knew I fucked up”….) Like wth does yesterday’s update after the market closes gonna do shit..? Can someone pls explain to me??

And yes I paid for a subscription on top of all that 🙄
