I am using Mathematica 12.1.1.0 and am having a really annoying issue that when I type an equal sign = it changes the input type in line so that I can't enter == to use in Solve or Reduce. Similarly, any time I use a greater than symbol, >, it converts to Python input. This is making working very very frustrating and tedious.
I have already re-downloaded and re-installed the most up-to-date version from my User Portal. Does anyone know what to do??
