Unable to sync LDS Tools on iOS 11

HI,

I tried to sync LDS Tools this morning on both my iPad and iPhone and was unable to get the app to sync on either device. The message about “Downloading …” comes up and immediately disappears. Both devices are on iOS 11 and are running version 3.2.1 of LDS Tools. Anyone else having similar issues.

Please help.

I did not find the right solution from the internet.
