Why isn’t my JDG device recognized after updating to iOS 26.4? Category : Specification / Capacity / Performance The JDG series has been discontinued for several years and supports iOS versions up to 26.3 only. Devices running iOS 26.4 or later are not compatible. We recommend using the device with an earlier iOS version for proper functionality. Is the answer helpful? Related Can I upload photos directly from the JetDrive Go to Facebook or other communication applications? Or do I need to import them to my iPhone before uploading? Why do files occupy more disk space when saved to flash drives/external hard drives/solid state drives? Why does Transcend include the Proposition 65 warning?
