Share Audio x 2 Powerbeats3 Headphones

I bought these headphones specifically for the Share Audio feature, yet my phone will only connect to one at a time. When I’m paired with one set and I try adding the second, my phone will try to connect to the second pair individually. The share option never pops up. I’ve tried everything I can think of. Using different apps, pairing and unpairing, restarting my phone, closing all apps... any and every combination of the aforementioned and NOTHING. I’m using an iPhone 11 Pro Max and two brand new sets of the Powerbeats3 Pop Collection Headphones. These are my first ever pair of Beats headphones (never owned AirPods either) and I am very disappointed! 😭
