My production is running on one "Blly EZSP" with late 6.10.X without group path that all EFR and MG1X coordinators is doing.
Before the system was adding the coordinator to listening to groups that was having 2 or more devices in on startup.
Old groups is having the coordinator added in the group and cant taking it away.
New groups dont have / getting it and its not in the list for adding it.
Example with 2 small groups old and new made:
Group information
Name Essecke Spot
Group ID 0x000b
Devices 3
Devices
Essecke Spot CWS3
Essecke · Endpoint 1 · No entities
IKEA Billy EZSP 6.10.7.0
Wohnzimmer · Endpoint 1 · No entities
Essecke Spot Remote
Essecke · Endpoint 1 · No entities
Group information
Name Essecke Tish
Group ID 0x0004
Devices 2
Devices
Essecke Tish CWS3
Essecke · Endpoint 1 · No entities
Essecke Tish N2 Remote
Essecke · Endpoint 1 · No entities
Some time ZHA have adding the remote to the group but its not needed.
Then scanning the groups and bindings:
Remotes have Power and pull controll cluster bond to the coordinator plus basic cluster to the gruop.
Lights is having OnOff, Level and colur controll bond to the coordinator plus basic cluster to the group.
All remotes is sending all commands to the group OK but the coordinator is not listeming on the group in the second example.
The lights is reacting OK on the command from the group and reporting ther status to the coordinator OK.
From HA start up log without debugging:

On the coordinator card is both the Light and SwitchGroup (with same functionality) but ZHA is not listening to the groups.
On test systems with Ziggurat all commands to groups is revived by the coordinator and if having devices in the group its being added to the coordinator card.
I dont knowing how to digging deeper in it and also i hope Ziggurat is going stable then my production system is being merged to it but its not there yet.
I think this its the reason some users is having problems getting commands from Bilresa remote in Zigbee mode.
