There is nothing wrong with the normal/advanced equipment setting. I am still set to advanced and still have my 3 Cleveland wedges equipped.. This is on both platforms. On my Iphone 8 Plus and my Samsung Galaxy Tab E the customize equipment option is set to Advanced and has stayed that was since I made the switch when they introduced the customize equipment tab.
The only difference in my equipment between PC and mobile is my Stand Bag Plus which isn't available on mobile, Everything else is the same.
Those ranting about not being able to have 3 wedges on mobile just haven't taken the time to really read the multitude of posts on how to switch the customize equipment tab from normal to advanced.
