Kameleon buttons may be hidden if Office application language or user account has been changed.
Office may also request the Kameleon add-in update and after that the Kameleon button is no longer available.
To resolve these issues Go to File > Options > Trust Center > Trust Center Settings > Trusted Add-in Catalogs select Next time Office starts, clear all previously-started web add-ins cache click Ok and restart Office applications. This setting will clear all Office applications sideloaded add-ins cache except Outlook.
