Issues with SD auto-backup to WDWP after first day of use

Yes it was strange and disapointing for me. I was so excited about using WDWP. Since it didn’t work for me with my Sony AX53 4K video files and with my Lexar 1000x SD cards, I returned the device to Amazon within the 30 days return limit. Instead I now use a $35 Ravpower Filehub Plus, even though that one has only 11MB/s SD to USB hard drive transfer speed. Still it seems to let me transfer a 256GB SD card over in 6.5 hours thus I can backup an SD card to a hard drive overnight. And I will also look at the Hikvision W100 Mobile NAS to see if that one might increase the SD to USB Hard drive transfer speed by a lot hopefully. I also will look at what WD might come up next if there might be a WDWP2 with some of the features that I have asked about in my other thread Wow, WDWP seems awesome, should I buy it?
