How do I change clubs in June's journey?

The three dots say Disband and that doesn't allow me to leave the club.

Same here

Wanting to know consequences such as losing gold and other rewards earned

You might be 'King' of the group. If that is the case you need to pass on the role to someone else and then you can leave the group

If you are president/leader of the club, tapping the 3 dots will say "disband" in gray. You can either remove all members, and then the "disband" will be green and be able to tap OR you can promote an officer to your position and thereby demote yourself and be able to "leave" when you tap the 3 dots. Except for league blue ribbon points, all rewards that you have claimed, including gold, energy and drink upgrades, will go with you to the next club.

Hi Ms. Tearius, does that include keeping drink tips if I switch clubs?

It will not allow to leave and I am not the president or any officer of the club. Very frustrating!!!
