Sync Issues in the default inbox

On my desktop, I’ve processed a bunch of drafts out of my inbox.
On my iPad and iPhone, those Drafts remain in the inbox.

Both iOS devices mirror one another. Both are outdated versions of the inbox.

Please advise.

Are all devices connected to the internet and logged into iCloud?

Is sync just completely stalled? e.g. you create a new draft and it is not syncing as well?

If so, start with the sync troubleshooting steps in the guide and open a support ticket if it does not resolve.

All settings were correct.
Reboot of all devices seems to have solved the issue.
Thank you.
