DHCP Snooping issue after 12.0.13.8 Upgrade

Question

Hello people,&nbsp;I just upgraded my M4300-52G to the last firmware version and as soon as the switches rebooted none of my devices were able to get an ip from my dhcp servers. Until I turned off DHCP Snooping.&nbsp;I checked my conf, but Trust Mode was correctly enabled on the Lag that goes to my dhcp servers's switch (and the 4 ports within the LAG).It was working perfectly before the upgrade and I did no change to my conf, so for me the issue comes from the new firmware&nbsp;&nbsp;&nbsp;DHCP SERVERS&lt;==&gt;SWITCH (LAG 1)&lt;=========&gt;(LAG 3) M4300-52G&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; No dhcp snooping&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; DHCP Snooping On, LAG3 Trusted.&nbsp;Does anyone else has/had this issue ?&nbsp;Thanks for your feedback ;)
