So, my friend, on the same twitter version I am, has a different tweet button than I do. He says it comes at chance as his tweet bar changes randomly, such as mine, but I never get this tweet button. Does anyone else have this tweet button?
Sometimes Twitter, and other social platforms, test things out. And some people see them and some don't. Maybe Twitter is just testing new buttons and colors. That is all
I have the screenshot on my phone. It seems they even changed the coloring of the top menu bar. This is all on Android, btw. The screenshot itself is too big to upload it says, so I cropped to the button. These are his screenshots.
