Sending money through them still seems to be OK, mostly. But holding funds -and similarly to the Chase stories in this post- seems to be risky business, if you don't fit a cookie cutter model of a business (for whatever Wise's definition of that is). Ironically if you're using Wise, you probably aren't a cookie cutter business in the first place, so I don't know what's going on with them.
Anecdotally it definitely also seems to be related if you deal with the third world much, as the linked OP below and myself are. Luckily the worst I've come across is arbitrary extra KYC popping up exactly as I'm needing to do time-sensitive transfers.
