Signals service disabled for my account — checkbox greyed out in MT5

Hello. The Signals service appears disabled on my account. In MetaTrader 5 → Tools → Options → Community, the "Signals" checkbox is greyed out and cannot be enabled, on several different computers and also on a fresh Windows Server install. Market and MQL5.community login work correctly with the same account. My phone is already verified. Could you check why the Signals service is unavailable for my account? Thank you.


Demo and cent accounts cannot subscribe to the Signals service, use a real trading account.
