Cable modem/router -> Ubiquiti Unifi Flex Mini -> 2 Unifi access points
Cable modem -> Miktrotik Hex S -> Unifi AP
-> Unifi Flex Mini -> Unifi AP
My experience is that switches ether work or they don't, although I have seen some weird problems with some really old switches (that probably had a bad memory chip) that would create a lot of corrupted packets.My wife told me the internet has been terrible all day so maybe it wasn’t the switch after all.

I have Unifi Access points at home, but don't use any Unifi (or any Ubiquiti, e.g. edgemax) switches, I have a mutt network of MikroTik, TP-Link, and Netgear vlan-aware switches, plus multiple "dumb" switches (TP-Link, TrendNet, even a bottom of the barrel Tenda 5 port 1Gbps). My main home router is a Ubiquiti ER-X and I have a "lab" with several ER-X's and an RB760iGS. I use a Raspberry Pi running the UniFi controller software instead of a UniFi CloudKey for the UniFi Controller.I like what I saw with the Mikrotik router. I originally got it because my Unifi network application changed IP addresses and I had some difficulty communicating that with the Flex Mini switch. There is a recovery mode where the switch checks for firmware on a static route, however I was unable to use that subnet with the Virgin router. Hence the Mikrotik.
Do you think this is a configuration problem or something to do with the router's modem mode? How would you recommend I debug the issue?
