App states regular_low and regular_high not syncing after archiving chat

[MiguelArgentina]

In our app we are trying to add the archive chat feature for every message we send.
The first time we archive the chat, it works, but after that, every other message sent fails archiving with the errors shown below.
This is a part of the function where the message is sent and archived:

        userJID := types.NewJID(phoneNumber, types.DefaultUserServer)
	message := &waProto.Message{
		Conversation: proto.String(messageContent),
	}
        ctx := context.Background()
	resp, err := client.SendMessage(ctx, userJID, message)
	chatID := resp.ID
	messageTimeStamp := resp.Timestamp
	lastMessageKey := &waProto.MessageKey{
		RemoteJid: proto.String(userJID.String()),
		FromMe:    proto.Bool(true),
		Id:        proto.String(chatID),
	}
	archiveChat := true

        archivePatch := appstate.BuildArchive(userJID, *proto.Bool(archiveChat), messageTimeStamp, lastMessageKey)
        err = client.SendAppState(archivePatch)

And these are the errors shown in the logs when client.SendAppState(archivePatch) is executed:

<?xml version="1.0"?>
<collection has_more_patches="true" name="regular_low" type="error">
  <error code="409" text="conflict"/>
  <patches>
    <patch><!-- 867 bytes --></patch>
    <patch><!-- 1175 bytes --></patch>
    <patch><!-- 1021 bytes --></patch>
    <patch><!-- 1313 bytes --></patch>
    <patch><!-- 1329 bytes --></patch>
    <patch><!-- 1021 bytes --></patch>
    <patch><!-- 1021 bytes --></patch>
    <patch><!-- 1021 bytes --></patch>
   ...
  </patches>
</collection>

I also tried resyncing the patches (before archiving) with:

        for _, name := range appstate.AllPatchNames {
		err := client.FetchAppState(name, true, false)
		if err != nil {
			client.Log.Errorf("Failed to do initial fetch of app state %s: %v", name, err)
		}
	}

but I get these two errors:

[Client ERROR] Failed to do initial fetch of app state regular_high: failed to decode app state regular_high patches: failed to verify patch v897: mismatching LTHash

and

[Client ERROR] Failed to do initial fetch of app state regular_low: failed to decode app state regular_low patches: failed to verify patch v712: mismatching LTHash

Does anyone have a tip on what this could be?
Maybe I should recalculate the LTHash? If this is the case, how can I do it?

I had the same issues @MiguelArgentina. After investigations, I think it has something to do with app_state_version in the db and app_state_version stored in other device. If one of them has flaw app_state_version, it will affect all devices with the same JID.

My quick fix was disconnecting all devices that connect to my WhatsApp and deleting the db.

Thanks a lot for sharing! I'll have this in mind. The thing is that we have close to 100 users, and deleting the DB would be something to avoid.
