Mobile device display issue

Salaams Brother,
Mashallah the plugin is really great but we are having one issue specifically on android and iphone devices. Its not showing today’s date when we open our home page. Even if I keep reloading the page, it keeps showing a day before. I even clear the cache and cookies but it doesn’t change it. I have to modify the URL by adding something after https://www.mcws.org?cacheburst=12345 or any dummy text and then it shows up.
The same thing doesn’t happen on desktop browsers.
I am not sure if its a problem with the plugin or the device setup. We tested with quite a few devices and it shows the same issue with every one
