Tumblr Not Working on Mobile Data, Only Loads on Wi-Fi

I’m unable to log into Tumblr using mobile data, and it only works when I’m connected to Wi-Fi. This is really inconvenient because I can’t always be connected to Wi-Fi. When I try to open the site on mobile data, it gives me an error. If I attempt to log into the app, the loading symbol shows up, but the app never opens. When I log out and try to sign in using mobile data, I get an error saying, “Something went wrong.” Tumblr, please fix this issue as soon as possible. This problem needs a solution so users can access the app without being dependent on Wi-Fi.
