The confusing thing with both browsers simultaneously is, that on non-SS androids one ACCount (called 'Samsung Internet' / blue Saturn type planet symbol) is sufficient for both the SSIS and the SSIB sync, while on SS-androids two ACCounts are required (the 'Samsung Internet' / blue Saturn type planet symbol for the SSIB and an 'Samsung Account' / blue and white man torso icon for the SSIS browser. I tested a fresh account with 2 Samsung and 2 non-Samsung androids and after some hickups both browsers synced the bookmarks an all devices in both browsers through one SS account. ) and wanted two browsers for side by side views. I tested the Sammsung Internet Standard (SSIS) and Samsung Internet beta (SSIB) browsers bookmark sync more thouroughly, because I like the browsers (ad-block extensions, tabs also on smaller devices, bookmark features, clean start page. The SS acount sync process seems unreliable every once in a while.
