User reviews

Cannot transfer files

The app connects to my X4 without too much issue, but then it won’t transfer files. I tried this numerous times on multiple networks, different settings, and no dice. Unfortunately, I may have to just refund.

Response from developer

Thanks for your feedback! I’ve also been able to reproduce the XTEInk file transfer failure issue on iOS 26, and have attempted to fix it in the upcoming version 2.0.2. Since this app is not officially supported software, I can’t guarantee that the file management feature will work 100% reliably at all times (though I’ll do my best to keep it functional). If this is a critical requirement for you, please request a refund. Feel free to reach out to me anytime if you need further assistance: biyebaby@icloud.com. Have a great day!
