Hello,
I do not see any problems on mobile – https://prnt.sc/p5yubf Please clear all cache and check one more time.
As a rule, the update doesn’t cause any problem, just follow our documentations https://www.8theme.com/documentation/xstore/theme-installation/theme-update/ https://www.8theme.com/documentation/xstore/plugins/plugins-update/
Please note that any Core plugin update requires the theme update to the latest version before the plugin update.
Feel free to ask if you have any other questions.
Regards
