I noticed when editing test cases using the side edit feature, that customizations are not being saved once I select Save. I noticed it once I added tags, hit Save, then viewed the test case in side edit view again: the tag was gone.
We are experiencing the same
When editing the test case via the edit feature within a test run, all fields update apart from 1. I’ve checked the settings for the customised fields and they are all the same, so shouldn’t be any reason why some update and other’s don’t save the changes.
