Nordic not responding to LL_FEATURE_REQ from central

We are seeing an issue with Android 13 on Samsung phones connecting to our device over BLE. After CONNECT_IND the phone will attempt to send a LL_FEATURE_REQ. It takes about 6 attempts before it is ACK'ed by the Nordic. Once the Nordic ACK's, it does NOT respond with LL_FEATURE_RSP. In the images below I attempt to connect twice, both fail. The detailed image only shows the time around when one the LL_FEATURE_RSP is received by the Nordic and then there is no response. This process is successful with the same Nordic/FW but with different phones. On other phones the first packets are typically a LL_VERSION_IND exchange.
