How do you edit vertices that are common in two adjacent polygons in QGIS?

I tried to select both polygons but when editing the vertex moves only in one polygon and not in both.

Once in edit mode, select the vertex tool, then on the snapping toolbar, select enable topological editing and at last left-click once on the shared vertex, move them, click a 2nd time to set the new location.

Since QGIS 3.20, there is a new possibility that allows exactly what you want: Select vertices by polygon.

With vertex-tool enabled, press the ALT button and left-click once with the mouse on the canvas. Than release the ALT button and draw a polygon around the point(s) you want to move. Finish your polygon with right-click. Then you can move the selected vertices: even without topological editing activated, vertices for both polygons will be moved.

Screenshot: Color is set to transparent to show that there are no overlaps. 1) Press ALT, than make a selection of the vertices you want to move, 2) Vertices are selected, 3) Move selected vertices, 4) Now polygons with moved vertices: enter image description here
