Bottom toolbar: tab icon no longer displays tiles of open tabs

I have been using brave for approximately a year.

I keep many active tabs open rather than bookmarking specific sites. I use the bottom toolbar to navigate between tabs.

Up until today, when I selected the tab icon from the bottom toolbar, the interface would show multiple tiles.

Today, the interface switched to just show a list of open tabs.

Picture#2 - screenshot from my wife’s phone which still displays the way I want to display

I must have inadvertently changed a setting that I cannot seem to find it? Please help.

Using: brave 1.24.86 chromium 90.0.4430.212
