Which theme are you using when this happens? You can find the name of your theme directly in your Shopify admin under 'Online store > Themes > Current theme'.
If you're using a Shopify-developed theme (like what's listed here), our team can certainly help look into this further. However, if you're using a third-party theme instead, I recommend reaching out to your theme developer about this directly by following the steps under 'Paid themes' here.
In the meantime though, when you tried this out on Firefox and Edge, were you using the latest versions of these browsers? Check out this help document for more information on this.
I hope to hear back from you soon with the above details!
