Sadly a never-ending problem. Had this since launch and it's only gotten worse. I have legitimately tried every solution I've seen online. All of it.
None helped. It's a problem between syncing your profile and the server after any changes are done. Even a single cosmetic change or a weapon swap that's not properly updated/synced will cause the issue.
Beyond frustrating and un-fixable as it stands today.
