Same symptoms here - have had this player for just over a week and it’s hit and miss. Sometimes is will go a day or two without losing the settings, then other times it resets almost everytime you power cycle the device. I use this mainly for listening to FM radio through a motorcycle intercom system back and forth to work, so it’s a royal PITA having to rescan for FM channels each time I turn on the player.
Has anyone reported this to Sandisk? Have they responded to anyone on this thread? I have had trouble with their firmware and/or drivers in the past on memory card readers. I work for a software company and if we let product into the wild that had this many problems, we would be bankrupt by now. Hopefully Sandisk tech support is reading this forum and will address this quickly with a firmware update - otherwise this Express will be going back to the point of purchase for a refund and I will be done with this brand altogether…
