When it came to wishing Prince Harry a happy 40th birthday via social media, King Charles III was "happy" to send the message. However, His Majesty is reportedly still harboring trust issues with his youngest son thanks to his Sussex 75th birthday phone call last November,

Prince Harry and his father, King Charles, might not be close right now, but the king is reportedly always willing to let Harry in and Harry’s frequent visits are a ‘good sign’ for the future.

According to royal expert Rebecca English, when Charles turned 75 last year, Harry rang up his dad, but the fact that the conversation and details of their call hit the news was a sore spot for the king. English explained that Charles was happy to call his son this year, but is still being careful with everything between himself and Harry.
