Not all Google cast devices showing (on new HASSIO installation they are present), how to?

HI,

In my “old” (but currently used) HASSIO instance (0.77.3) some Google Cast devices (mainly groups of Google Home and Chromecasts audio) are not present. Remove the Google cast integration and restart HASS did not work.

Yesterday playing with a new HASSIO installation noticed that all the groups were instantly recognized, but I am unable to make them recognized by my current installation.

Anyone know my option?

MAybe cancel/modify a file somwewhere?
