Please don't cross-post to multiple channels, that wastes the time of anyone reading the message multiple times and splits discussions. Pick one appropriate channel according to name and subject and at most post a link in other channels if you really feel you need more attention.
Especially as this channel's topic is not at all related to your question in any way.
And more importantly, don't DM people with the same message, that is extremely rude and against common sense, and the written community guidelines.
