Hello, Kiki,
We didn’t make all opened tabs on mobile but made changes to scroll to the tab content area so that on tab click the window will be scrolled up to the area with its tab content.
There is no compatible solution for your case at this moment to keep all tabs open. You may change the type of tabs to another from the available -> https://prnt.sc/ADNYmZheJjWO
