iOS Notification sends me to the wrong chat

When I open a notification of a new message on my iOS lockscreen it sends me to the wrong chat. I type a message and then send it to the wrong person. What can I do to fix this? Has anybody else encountered this problem?

There isn’t any deep linking within the app. Currently it opens the last channel viewed.

There is https://mattermost.atlassian.net/browse/PLT-1549 which is tracking the feature request for deep linking.
