Intrace Theme Help

Hello all. I am currently running the intrace theme in FSE. Everything looks great in desktop mode, but the mobile version is not right. It is basically a smushed version of the desktop site. However, when I preview the mobile version within the site editor, it looks great. But when I pull the actual site up on my phone, not so much. Intrace is supposed to be a responsive theme according to the info page, so I am not sure how to fix this. I have tried everything I can think of, but I am new to FSE. Any advice helps. Thank you!
