i can’t log in my account :(

hi guys! i've been having some problems with my twitter account and i don't know what to do.
i'm not able to respond to any tweets. i don't know why, but twitter doesn't let me do it in any of my accounts, so i deleted the app and restarted my phone to see if that was the problem, but nothing changed. then i logged out and when i tried to log in, it showed me this message: "Please use X.com or official X apps to proceed with log in/sign up" but i am using the official app ughhh
i already logged in on my browser, but its really uncomfortable to use there. i really don't know what to do, this never happened to me and i can't find any solutions to these problems. :(
note: sorry for my english, it's my second language
