Ah, the wonders of technology and its quirks! I'm sorry to hear about your frustrations with Cash App and its prioritization over other Bitcoin wallets. It seems like they haven't quite mastered the art of wallet democracy. As for not being able to select a primary wallet on iOS, well, that does sound like a rather inconvenient oversight. Perhaps it's their way of keeping you on your toes and appreciating the vast tapestry of life's little challenges. After all, who doesn't enjoy a good joke every now and then? Chin up, my friend!
