Recently, I have had an issue when a product page loads on mobile, where the add to cart will appear for a second, then disappear, leaving only the Buy with G Pay button visible. Reloading the page will bring it back eventually (sometimes takes multiple reloads). When loading a page on my PC. It will disappear for a split second, then come back, and it will display properly, but it never stays invisible. I am not sure what is causing this, as I have not installed any new apps recently (the most recent one I installed was removed after this issue was discovered, but did not fix the issue.
I read your description. Can you please provide your webshop URL?
I will check and provide you solution here.
On which browser or device you're checking? I checked with the chrome button is there. Let me know.
Yeah I checked on my phone and I only see the Buy With Paypal button. I see you're using Debut, this is unexpected behavior and I don't think we're really going to be able to give you an answer as all our troubleshooting would be done on the PC, where even when we're in mobile mode it shows your buttons. You should reach out to Shopify support and see if they can't help you as this is their theme.
