I have a Sandisk Extreme Portable SSD 500 GB. It works fine with Windows 10 but it cannot be detected by any of my Android devices. I tested with an Nokia 3.1, Sony Xperia Z3 Tablet Compact and a Sony Xperia 10 Plus, both with and without a Transcend OTG adapter. As well, I reformated it with exFAT and NTFS. What could be wrong?
The tablet runs Android 6 while the two phones run Android 9.
Other USB memory sticks work fine with the OTG adapter on all devices.
