It is kinda common to not see traction in HA core issues.
There are so many issues and responses that trying to reply and be active in them will kill the time for actually solving the issue.
You might actually at some time the bot closing your issue, due to it being stale.
You might suddenly get an update to code and then your problem is fixed.
What is important here is to provide as much info as possible with as much testing as possible, because that makes it easier for the devs to actually understand the situation and maybe also see the reason, so they are more likely to solve it faster, simply because it is an easier problem to handle.
