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
