Nope, not working on my end.
Had iphone 7 (two of them) running ios 11 without issue.
Just upgraded to the lastest 11.3 today, and nothing is working now (says ibase not connecting).
Also just bought an ipad pro 12.9, and updated to the latest ios 11.3 out of the box. Then I downloaded ibase app, and it did not charge or recognize the base.
My phones were charging fine on third party lightning cable. Now it does not recognize the cable any more (says this accessory is not supported and then stopping the charing process).
I am certain that this is a new ios issue, and not a software issue.
I went to the sandisk website and followed their instruction: uninstalling, reboot, and ininstalling the ixpand base app to no avail.
So disappointed for such a good product.
