eero 2.4GHz network gone!

I have 3 eero Pro 6 and earlier today everything on my network that uses 2.4GHz got disconnected. I wasn't able to reconnect any of those devices to the eero network. Only the 5GHz devices were still connected. I restarted the eero network several times and nothing worked. I had to enable the 2.4GHz radio on my ISP modem so everything else could work again except for the Blink module which now won't connect to anything. Checking with a couple of apps; WiFi Explorer Lite, and WiFi Analyzer, there are no 2.4GHz eero networks. Is that right? With my ISP router you can see both 2.4 and 5GHz. I don't think there's a way to disable the 2.4GHz radios on the eeros. I saw something about disabling temporarily the 5GHz ones so devices that use the 2.4GHz network can connect. A new firmware update was just installed on the my eero.network this week. 6.13.0-3760. Does anybody know how to fix this?
Thanks.
