Thanks @akamud for sharing your bug. @Oddj0b would you mind taking a look at this?

[akamud]

Hi, do you have anything to comment on this? This makes writing UI tests for iOS really cumbersome (the only workaround is downgrading to use the REPL and upgrading to fix the connection problems).

[Oddj0b]

@akamud Is this still an issue with Xamarin.UITest 3.0.4-dev4?

[akamud]

Let me test and I'll get back to you.

[owenniblock]

@akamud there's a new version of Xamarin.UITest and TestCloud Agent out today - if you haven't already retested - please could you try these versions?

If you have - let us know how it went :)

[akamud]

Great to hear. We will work on this again possibly on the next sprint starting next week.
