This has been an issue for many years but it's more noticeable with the reduced traffic since it's easier to watch every packet on the network and see patterns which is why I didn't notice before
I noticed all the queriers get synchronized so they all try to refresh the A record at the same time.

To avoid accidental synchronization when, for some reason, multiple
clients begin querying at exactly the same moment (e.g., because of
some common external trigger event), a Multicast DNS querier SHOULD
also delay the first query of the series by a randomly chosen amount
in the range 20-120 ms.
