This might help slightly….
Not to drive you away from homey and to Home Assistant but the Thread tool on that helped me see the networks and mamage them. I found i had multiple. I found one was totally locked but others could join it.
Make one “thread mesh”
If like me Its confusing, i used google And chat gpt and its been solid since - for the first time ever.
Are you in Homey or SHS?
The homey app (for pro) will show you your preferred network. I believe Aqara can be made to mirror/extend an existing thread network. But you WILL have to delete all devices on the aqara hub to do it. Its not a short process but its worth it
