We implemented our own ActionChain that works in Safari 13. In Safari 14 it's not working anymore. we use a POST-Request to the safaridriver binary (we tested technology preview and the standard one) to the session url "session/{{sessionId}}/actions" with JSON { "actions": [ { "type": "pointer", "id": "touch", "parameters": { "pointerType": "touch" }, "actions": [ { "type": "pointerMove", "duration": 0, "origin": "viewport", "x": 10, "y": 20 }, { "type": "pointerDown", "button": 0 }, { "type": "pointerUp", "button": 0 } ] } ] } this request returns { "value": { "error": "not implemented", "message": "", "stacktrace": "" } } in Safari 14. In Safari 13 it gives the expected { "value": null } and the action is executed.
