Hi Nordic,
We are develop a multiple switch button device based on nRF54L15. We've two issues now while developing.
1. Matter Network Commissioning Issue with nRF54L15 DK
Using the nRF54L15 DK, we have implemented a multi-switch functionality. However, the DK behaves inconsistently in different testing environments. Even when using the official unmodified demo applications (such as light_bulb and light_switch), the issue persists.
We have submitted a support case on the SmartThings community website, which includes a detailed description of the issue and log outputs. However, the feedback so far has not resolved the issue.

2. Multiple Fabric Issue
The multiple fabric feature also shows inconsistent behavior depending on the environment. This issue also occurs when using the official unmodified demo applications (light_bulb, light_switch).
We would greatly appreciate any help in analyzing the root cause of these issues or any suggestions you may have. Thank you in advance for your support.
