The store is in dev right now but we are facing an issue with the checkout on chrome android, a weird auto scroll/jump to top. We tried on other mobile browsers but cannot replicate the behavior, only on chrome. Also on desktop all is ok.
If you scroll down from time to time the scroll will go instantly to top and this is a problem especially in checkout since you cannot fill in the details required because it will scroll to top.
magento 2.4.2 with Porto theme 3.2.5 and for the checkout Amasty One step checkout.
