Hello,
I noticed 2 issues with chat retention days.
1. There are separate settings to set up chat channel retention days
and chat dm retention days
. But it seems it use the chat channel retention days
value on personal message settings page too.
I setted up 2 different retention day.
The chat retention reminders in messages show the correct value.

2. When the chat channel retention days
and/or chat dm retention days
set to 0
it means retain messages forever. But now on (channel / personal) retention day messages it seems like it saved for 0
day.
Thank you
