Why has my mobile page shrunk after connecting to Google and YouTube apps?

Store Design
1

Hi, I just connected my store to google & YouTube app. Ive connected my site to all the Google apps (merchant centre, search console, tag manager, etc). Since connection all the body text has changed style and my mobile page has decreased in size totally (pictures & text) and is un-useable/does not work. it loads the home page but cannot navigate anywhere from here using the page dropdown tab.

Hoping someone can help.

That would be rather strange if its from connected accounts, because non except for tag manager, can change the website info.

Check i fyou have not added anything in Tag Manager, but I think contacting the theme developer would be the best way forward.
