Hi,
Could you create a new perspective and delete the default.
1. Creating a new perspective (in which the already added resources were visible in the Resource Explorer view)
2. Adding them to the new Resource Explorer.
3. Deleting the default perspective.
If the SCC is 3.2.6 and below, please install the latest version of SCC(ex 3.2.7).
And let me know if the problem is still happening.
Best Regards,
Gi-Sung Jang
