ok, I solved it, or rather João did in another thread. For some reason it doesn’t work if the recording is faulty which was my case because I didn’t pass 3 km/h on my test walks. But when on bicycle (my motorcycle is not in use during winter) it actually works and file name magically becomes correct also! Great news (don’t know about the overwrite thing but that will not be a problem if the date/time stamp is working)
