Navi and no end

Good morning , In addition to the here already described “problems ” with the Navi I would like to attach here also again the following problem which I can not explain to me .. ( Arona , Built 2022 ) My daily way to work drove over city , BAB , federal road (well developed) Now the federal road is for at least 6 weeks fully closed! In the first week no report of the blocking in the Navi , standard route was proposed . Second week to today , sporadic display of the blocking , tägli A second possible redirection does not come at all via the Navi (more federal road, but even better developed than the standard route ) All systems are paid 🙂 and online is up to date. The “learning function ” of the Navi is activated. What can this be on ? Mfg Mathias
