IKEV2 two devices can connect but only one can make traffic

If I use the "dynamic keyword I get this error: "no IP address found for
dynamic" though "config address 192.168.98.1/24" is there.
Using 0.0.0.0/32 instead of 0.0.0.0/0 causes that traffic is not routed
('cause /32 restrict the only address possible to 0.0.0.0) though
connection happens correctly.
