Hello @Farcela,
I have reviewed your website and have not identified any issues. I have tested the same product on my personal mobile device and on the Chrome Inspect Responsive Tool. I have observed that the added product notification type is a popup. Please ensure that you always check the website’s responsiveness on a real mobile device. I have recorded a video for you on your website. Please watch it in its entirety for better reference:
