Hi, I recently tried Catalina beta 7 and Xcode 11.0 beta 7 and ran into some problems. When running mini-browser loading fails in WK2 (works for WK1) with the following Inspector message: Failed to load resource: A server with the specified hostname could not be found. Also many loading related tests fail or timeout. Did anybody try a similar setup or can tell if I missed a setup step? Could it be a sandbox issue and/or is Python 2 or 3 choice important? Cheers, Rob.
