I have two of those paired with a Hubitat hub (and then an integration that gets the Hubitat stuff into HA). Over on the Hubitat forum there’s a thread where people are finding that pairing the button again (without unpairing it) seems to solve that problem. Sometimes it fixes it after the first re-pair, sometimes in takes more than that. I think one of my buttons worked after the first re-paired. The other it took like six tries.
