We’ve experienced the same issue after upgrading our switches to 18.1.2. Wireless clients connected were not receiving DHCP addresses. Once we rolled back to 17.2.2, everything returned to normal. For context, SecurePort is enabled in our environment, and we confirmed the problem was isolated to MS130 switches only. Other switch families (MS225/MS250/MS425) didn’t show the same behavior, or at least weren’t affected in our case, as only four of our sites upgraded and we primarily use the MS130 range. We’ve logged a case with Meraki Support so they can investigate further, as this seems consistent with the regression others have described here.
