Mobile theme showing on tablets

Hello, We are using Newspaper theme version 10.3.9.1 on our multisite, with WordPress version 5.6.1.

We are having the same problem as described in this other post https://forum.tagdiv.com/topic/mobile-theme-also-showing-on-ipad-viewports/, when we view our website on a tablet (iPad, Kindle Fire, etc) the mobile version of the website displays instead of the tablet view that we set up in TD Composer.

In the other thread, the suggested course of action was to check WP Super Cache settings, but we have set up WP Super Cache according to the directions on your support page. We’ve also tried disabling all plugins in case there was a conflict.

Here is some more info from the system status page, please let me know how we can fix this, thank you.
