Windows 10: Updated Twitter app changed language. Unable to return to English

I used the previous version of the twitter app on windows 10 without problems. My preferred language was English and so was the interface. After updating to the new version of the app, the app now has an interface in Hebrew and displays from right to left. I've done all I could think of to change it back to English and left-to-right direction but nothing works.

• The language selected in the app Settings is English.
• The Windows 10 display language is English
• I uninstalled and reinstalled several times, both through Apps and Features and PowerShell. The newly installed app immediately logs into my twitter account. Since I completely removed the app from the pc, where does the app take that login info from? Are there settings files hidden somewhere that control the way the app behaves and even override the in-app language settings?
• I even searched the registry for my login info but didn't find anything meaningful.
• I also tried changing locale in windows itself. It too didn't work.

Any suggestions will be greatly appreciated.
