The digital ocean droplet for Mattermost (https://cloud.digitalocean.com/marketplace/) is currently at v 5.16.3.

Their website says some features for versions earlier than v5.19 might not work as intended.

[Starting with mobile app v1.33.0 releasing on July 16th, users connecting to server versions below v5.19 may experience compatibility bugs with how attachments, link previews, reactions and embed data are displayed on their mobile device.]

I keep getting the same error on my app too - “Server upgrade required”

Will Mattermost update the droplet? Should I follow the instructions on https://docs.mattermost.com/administration/upgrade.html to do it?
