Issue since upgrade to v8.0.0.54216: css troubles (bootstrap and mxui)

Hello Dear All, I have some troubles with application "Task" kindly published on Mendix app store ( Since the last update of Mendix platform (yesterday the 9th of July 2019, v8.0.0.54216), there are some troubles related to CSS resources ?  (lib/bootstrap/css/bootstrap.min.css and mxclientsystem/mxui/ui/mxui.css) It seems, regarding release notes, that bootstrap is no more included… for mxclientsystem, I don’t know the reason.  Maybe, do you know how to solve that ?  Thanks in advance !
