App becomes amazingly slow and often force closes

[giffmann]

Summary

The app, over the past year has continued to degrade and become agonizingly slow over the course of a week or so of usage. I, and numerous other people at my organization, have been forced to delete/reinstall the app as often as every 2 days in order for it to continue working. The slowness exhibits itself when selecting a channel to respond to. It can take over 5 seconds for user action to be recognized and acted upon. Recently, the app has also started force closing when attempting to read a channel OR create a post.

Environment Information

• Device Name: iPhone 13
• OS Version: iOS 17.4
• Mattermost App Version: 2.14.0/2.13.0/2.12.2/2.12.1/2.12.0
• Mattermost Server Version: 8.1.7

Steps to reproduce

Use a mattermost server that has stats similar to the screenshot. Perform ANY action after using the app for a week.

Expected behavior

WAY faster responsiveness to user actions. NOT force closing itself.

Observed behavior (that appears unintentional)

No error messages ever. App becomes slow taking upwards of 5 seconds to respond to any input AND force closes itself.

@amyblais would be great if the team would take a look at this issue and the linked issue noted above. The original issue has been open over a year with no response and not even noted as a bug report by a label yet. This issue affects between 200 and 300 users at my org.
