I lost my left bud for Airpods pro 2s. So, i bought a replacement and followed online guides that say to unpair from phone then leave them charging for 20 mins then try to pair again. Problem is, now the airpods arent showing up in bluetooth at all. No matter what I do. Before, i could atleast use the old right buds with the case. Now that too isn't working. Im at a loss and panicking
