Can you show us the value of contentOffsetRegex in Xamarin.UITest.cs?

it seems there is contentOffset in description?

Yes, I don't see where the contentOffset is defined?

The regex to use can actually be found in the ruby script in line 15, though I couldn't test it yet in C#

@bill2004158, @bogdangm, @vatbub Yeah, I missed the regex in this GIST. The main point is the idea to solve issue, however, you guys could run it and define it after debugging the code.
