There was a issue reported to me by a very important colleague related to the To Do app running on his iPhone. When he tried to sync between the Traveler server and his device, he got this error:

After a quick call to IBM Support, I was given my answer:

There is a recently discovered problem in the ToDo app that causes HTTP requests to be malformed when the server redirects the requests.  A fix will be published to the App Store, however, it may take 1-2 weeks to appear.  In the meantime, the customer can avoid the issue by instructing the affected users to modify their account settings in the ToDo app.  In the space reserved for the server
name, please use company.com/traveler instead of company.com, for example.  This will avoid the HTTP redirects which trigger the problem and should allow the device to sync normally.

A quick fix, with a more permanent one coming… Well done, IBM!!!
