Have noticed this with manual scanning so might not be an issue when scanning against the database. Both rom and thumbnail names match but doesn’t seem to show thumbnails that include an “&”. Is this a bug and is there a workaround for this? I remember there being a similar issue with “-” and “_” but this was when scanning against the database.
That is just the naming convention for thumbnails in RetroArch. “&” need to be replaced with “_” in the thumbnail file name.

Highlighting the relevant sentence: The following characters in playlist titles must be replaced with _ in the corresponding thumbnail filename:** &*/:<>?|`
