Snapping to segments not working in QGIS

Question

QGIS 3.x does not let me snap to vertice and segment anymore, only vertices.

I changed the snapping options several times in the toolbar and in the options menu. Made sure the correct layers are activated. Restartet everything.

I even uninstalled QGIS 3.4 deleted all app data and installed 3.10 instead but the problem prevails.

I can not bring QGIS to snap to segment or follow an existing shape.

Does anyone have a solution?

I am familiar with the settings and choosing the right ones is unfortunately not the problem. Also zooming closer, or starting a new layer did not help. Neither did importing the layers into a new project.

Using standard CRS WGS84

To get the snap to vertices to work make sure you have the following options selected:

• Enable Snapping (U magnet button)
• Enable topological editing
• Enable snapping on intersection
• Enable tracing
• Make sure the projection for both layers are the same

I've provided a snapshot of the options to select below - this works on 3.4 and 3.10.
