Not working auto-renew at DHCP

Question

In a test lab, I was trying change ISP (Disconnect ISP1 cable and connect ISP2 cable). 
 It does not working. XG Firewall does not receive new IP. Need a manual edit for interface. 
 Why don't you to provide automatic renew? 
 test ver. is XG Firewall 16.01.1

Hi, 
 
 I try with the version 17.1.1 MR-1 and it is still not fix... 
 
 I got this answer : 
 
 As to the RFC, I am not at all suggesting the other vendors are not following RFC; in all likelyhood, they are following it just fine. One of the key words in the RFC is "SHOULD": https://www.ietf.org/rfc/rfc2131.txt 3.7 When clients should use DHCP A client SHOULD use DHCP to reacquire or verify its IP address and network parameters whenever the local network parameters may have changed; e.g., at system boot time or after a disconnection from the local network, as the local network configuration may change without the client's or user's knowledge. SHOULD doesn't necessarily mean MUST. So where some vendors may choose to do so, others don't necessarily have to. As to whether or not this is a bug, our DEV team has confirmed that this behaviour is expected, and by design; there's no avenue for Support to push back on them to fix this (since it's working as designed, there's nothing to 'fix').

I tried the auto-renew DHCP on the last version 17.5.1 and it is still not working. 
 
 No choice, I have to choose another product and I decided to go with Meraki for my 26 warehouses.
