Heya Emmanuel! First off: Welcome to the Mattermost forums! Second: I’m sorry to hear you’re experiencing these issues. Lemme see if I can help you with some troubleshooting steps:
Double check your Markdown Syntax. Even small errors can prevent proper rendering. Refer to the Mattermost Formating Guide to verify.
Verify that the affected users have proper user permissions and roles.
Clear cache and cookies
Ensure your Mattermost instance and all clients (web, desktop, mobile) are updated to the latest version.
Go to your System Console, review any settings related to markdown and link handling, and ensure support is enabled and configured correctly.
If none of these troubleshooting steps fix the issue for you, I’ll see if I can find your a better answer elsewhere!
