some how the call to dcContext.marknoticedChat((int) chatId) is getting stuck

[r10s]

thanks for figuring that out! so then sth. might be wrong in core, and there may be situations where
marknoticedChat() does not return immediately? cc @link2xt

btw, it is ANR, not ARN :)

"ANR" is an abbreviation for the spanish term "Aplicación No Responde"

oops! dyslexia! XD

chat::marknoticed_chat() only has 3 awaits and all of them are for SQL queries, though if it marks all messages in the archive as noticed, i think it may take noticeable time. Is this reproducible?
