[BUG] Visible all deleted/cleaned messages in channels

[avs-ru]

• Your Rocket.Chat app version: 3.1.1(214)
• Your Rocket.Chat server version: 0.69.2
• Device (or Simulator) you're running with: iPhone ios 10.2.1

After admin cleaning old messages in channel on desktop via browser (not standalone client, maybe same), or delete message from some user in channel users on mobleclient can see all cleaned/deleted messages.

Looked in DB for default channel "GANERAL":

db.getCollection('rocketchat_message').find({rid:"GENERAL"})
Fetched 0 record(s) in 7ms

Looks like all messages is cached on mobile, and no option for refresh (pulling down as example like in other messagers).

After some tests: logout, then login again = correctly view (not showing deleted/cleaned messages)

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:

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!
