In MC i was checking connection logs.I was walking all groups, and Device was changed to "Null" From this time I can not see any connection logs until I manually delete the "Null" string.
Can you confirm this as bug ?
I make screenshot to show what I mean:
When this NULL appears, and If you miss it now, and then go to another group, it is very intriguing, as it suddenly turns out that the specified range of time does not have any connections.
Thanks for your post and bringing this to our attention!
I tested your question and got the same results with no connection reports being shown for other groups if "null" remained in the device box.
This does not seem to be the desired action with connection reporting so I have forwarded this case to our Support team for further investigation.
As always thanks for your feedback!
All the best,
