I got the same "contact them in some time" response as well....

I think a SC staffer indicated SC doesnt have dedicated teams to each game. What that tells me is most resource efforts (ie human effort) goes into SCs flagship games Clash and Brawlstars.

I think HD is poorly supported and SC cant be bothered with issues not easily solved. I dont play Brawlstars, but things in Clash get fixed quick, unlike HD where issues clearly linger for some time.
