Dear support team.

I have a similar issue as mentioned in this thread:

Can you please share the answer/results you found during testing?

Thanks and Best Regards.

Hi Tim,

Does this behavior occur on multiple devices? I sent you a connection request - can you accept this request so I can ask a few more questions about what you are observing?

It would be good to get the top marking for the device so I can look into the lot history as well.

Best regards,

Matt

Good Morning Matt.

Thanks for your reply.

I observed this issue on the two boards colleagues are using for firmware development. We are implementing some safety measurements currently.

I will come back to you with the top marking of the devices as soon as my firmware colleague is available.

Best regards,

Tim

Thank you Tim. I think there should also be a 2 digit number which is the date code.
