I have installed FreeCAD (0.20.2) from snap on Ubuntu 20.04.5 LTS. I can not save files in my home directory, despite FreeCAD has enabled access to /home directory:

I have open document in FreeCAD saved as /run/user/1000/doc/cb5d929d/aa.FCStd I choose File/Save as and can access /home. I select some directory and enter name bb. When I click Save, FreeCAD does not complain about anything. Now document properties says that file is /run/user/1000/doc/630aade2/bb.FCStd name has changed but there is no bb.FCStd file in selected earlier directory.
How to save files outside of /run?
EDIT: I have updated info about FreeCAD version. It is stable 0.20.2 not 0.21 as I wrote originally
