Button Of PayPal Express Checkout Doesn’t Work On Every Browser

Dear respected Woocommercers,

I wish you’re fine. I noticed that the PayPal Smart Button (PayPal Express Checkout Plugin Button), doesn’t show up on some browsers like: Chrome Mobile 78.0.3904, Facebook 271.0.0, Opera, etc.

I want to use the PayPal Express Checkout only to record the conversion that come from different advertisement platforms, if I use the Standard PayPal Button (not smart button), PayPal will redirect the customer to PayPal website to pay but it won’t redirect the customer back to the store automatically after the payment to record the conversion and because I’ve more than one store and only one single PayPal, the redirect configuration at PayPal end won’t serve multiple stores, they allow only one website.

I’m using the Theme Storefont latest version 2.5.6 and I’ve tested the Smart Button with many other themes, it doesn’t work too, also tried to remove all plugins, the same problem. Any solution or workaround for this problem?

Thanks!
