This. Our courtesy corp network (for people’s personal devices) has a number of open ports on TCP. But almost none on UDP. Had to put an exception (favor really) with network security to open a port on UDP for my VPN
Some IsPs block WireGuard regardless of the port - I’ve got entry nodes on 53, 443 and a high port and some places (Egypt was quite common) block them all - I assume with deep packet inspection looking for the WireGuard headers
UDP can be blocked. Doesn't affect browsing DNS is local anyway.
However it's arranged generally rovust VPN requires being able to send TCP over a well known port - which Wireguard by default doesn't do.
So I'm currently looking for an Android VPN app which can multiplex via a long live lived TLS connection.
