Sure: one Mini (1st gen) is on 1.56.264660. I enabled others for the
preview program, they are now on 1.56.275994. That's also the version
currently on my preview enrolled Google Home device.
I've got the same issue, same firmware version. One additional
observation: The issue seems to happen primarily when the device hasn't
been used for a while (like 10 minutes). E.g. if I ask for the time, it
takes like 5 seconds before the dots start ...
