I recently purchased an Osmo Action Quick Release Adapter Mount from DJI as I am using them with both my Pocket 3 and Action 5 Pro.  It comes with an adhesive foam for a more secure fit.  This is exatly what the Ulanzi OA11 and OA12 adpaters should include as they are loose when connecting to the Ulanzi cage for the Pocket 3.

Thanks for sharing this information! It will definitely be helpful for others on the forum. Have a great day! Thank You!

Good to hear!
