Why Are My Microsoft 365 Integrations Not Syncing Across Applications?

I’m encountering issues with Microsoft 365 where integrations between applications are not syncing properly. For example, updates made in one app are not reflecting in others, causing inconsistencies. I’ve verified my settings and checked for updates, but the problem persists. Has anyone else faced this issue, and what troubleshooting steps or solutions have you found effective in ensuring seamless integration and synchronization across Microsoft 365 apps?
