I have installed the most current version of insync-caja (3.4.2.40983) and icon overlays are working, but it appears that overlay icons are only available for a subset of file types in the Mint 20.2 MATE Caja file manager, meaning that some files display correct overlay icons indicating sync status but others show no overlay icon. My guess is that there are no suitable icon files in the insync-caja release to replace the original Caja versions(?) This is occurring with even some rather common files types such as .pdf
If I use the Nemo file manager on the same machine then all file types show a correct overlay, the problem appears to be isolated to Caja.
Is this a known issue for insync-caja and Mint 20.2 MATE?
Thanks -
