Unable to Log into My Tumblr Account Despite Reinstalling the App

I can’t log into my Tumblr account and keep receiving an error message saying there’s an issue. I tried deleting and reinstalling the app, but now I can’t access my account at all. As you can see from the screenshot, this issue is ongoing, and it’s becoming really frustrating. I expect Tumblr to fix this problem immediately, or I will stop using the platform entirely. I’ve tried multiple troubleshooting steps, but nothing works. Please resolve this issue as soon as possible so I can regain access to my account.
