This issue is blocked because there's no way to get deleted messages via API.

@rafaelks But I don't need 'deleted' messages! I need only view messages are actually in channel.

Steps to reproduce:
1/ In channel lots of messages
2/ user go to channel on iOS client and read all of them.
3/ admin clear the channel via 'Purge' option or delete random messages manually

Result:

• in DB no messages.
• on desktop client user got empty channel.
• on iOS client all previously viewed messages by user in place. Only logoff/logon to server helped to get empty channel.

As I think (as not programmer) - there is no "refresh" action doing when go to previously viewed channel, only getting new messages without refresh (but if message was edited - all O.K., all correct).

@avs-ru There's currently no way to for the mobile apps get what messages got deleted. Can you show me the option you are using to clear the messages?

Sorry this internal server :(.
But I make some screens!

So, in empty channel "general"(in this example) typed two messages:

Then as another user (but i think login by different user not important) go to this channel on mobile

Next purge all messages from channel:


... and typed new message "Test3 afer prune"

On mobile go to previously viewed chanel "general", and got this:

@avs-ru Great, thanks!

+1
I really need this without logging out and in again

To update you guys on this thread: we recently shipped an API that will allow the mobile apps to support this. In near future you'll see this change in the mobile apps, please keep an eye on this issue. Thanks!

@rafaelks any updates on this?

I checked the latest heroku build (0.74.3) and issue persists.
However, on open.chat.rocket I already see a Message removed in place of the deleted messages (the behaviour is a bit buggy though, as it only refreshes by closing and opening the channel).

I know this is mostly a server issue so, by any chance, could you redirect me to the PR that introduced this behaviour? Thanks.

EDIT: since writing this I found out that the "Message removed" is tied to an admin config where you can "show the deleted status" (where the messages aren't in fact deleted but it's status changes to rm). However my main question still holds: is there already a way to correctly sync with the server and eliminate the deleted messages? Thanks!
