Hi Suraj,
No need to refresh the apps that make use of HTMLUtils.
However, when I tried the app that make use of FileUpload, it always return a no file found error after selecting the file. I created a sample app that makes use of the component. Please see attached.
Please note that we just migrated from P9 to P10 and the FileUpload version is different. The P9 version is still working.
Regards
