Not a regression.
See this thread. On the webapp it shows "Fastlane" correctly, while on the mobile app the display name is "Christopher Speller".

Hey @hanzei can i try this out ? I have worked with a bit of react native before.
Thanks
Sure, it's all yours @ThakurKarthik. :+1:

Hi, I have setup the android app and clicked on the thread for me it's showing the expected "Fastlane" string. Is the issue resolved already ?
@ThakurKarthik You are correct, that bug fas fixed already. Sorry for the confusion.
