For those who cannot connect the drive to iOS 10 devices

Hi , I have just bought a Sandisk media drive 32gig drive,  it refuses to connect to any of my iOS devices , however , after following your advice , I can connect it to my device WIFI , but here’s the problem , the app refuses to see the drive ! I’ve tried hundreds of different configurations in static settings , but to avail , when I open the app after the drive is connected , the WIFI lights flash , but no connection , tried this on both my old iPad up to new iPads and iPhones , not one will connect ! I’m pretty disappointed with this product, not one amazing review on YouTube covers these issues ! . Help .
