We now have multiple Mattermost server support in the mobile apps in Beta! If you're interested to try it out, here's how you can join the Mattermost Mobile app beta program.
The community feedback on the Beta version has thus far being excellent, and helps us improve the user experience before we ship multi-server support as a stable release to everyone :)
Really appreciate your feedback. We had intended to pause the admin advisor notifications couple of months ago but due to an intended bug some of the messages are still coming through. We've queued an update to pause them in the next release (v5.38). [1]
The original vision for the admin advisor notification feature was to guide administrators through proper activation and configuration of the system as the needs of their user base evolves, with some additional capabilities in the Enterprise offering. However, based on the feedback we received, it was evident that the experience felt spammy with limited value which was not the intent, negatively impacting the trust with our community. Hence why we've decided to pause admin advisor notifications at this time.
We offer a non-profit license for open-source projects [0] with special nonprofit pricing. We also plan to move the System Permissions Scheme into the open source Team Edition with the 6.0 release on September 15 [1].
Thanks for being a user, feedback is always welcome!
There is a hosted SaaS version of Mattermost as well. We don't have an established non-profit license for it yet, but you can contact community[at]mattermost.com and we'd be happy to discuss options.
