Arccos sensors keep falling off my clubs, anyone else?

I've been using Arccos for about a month now, and I've already lost two sensors. They just pop off when I pull clubs out of the bag or sometimes when I'm swinging. It's so frustrating. I'm worried I'm going to lose all of them and then the system is useless. Is this a common thing? I've tried screwing them on tighter but they still come loose. I'm not super techy so maybe I'm doing something wrong? Also does anyone know if you can buy just the sensors without the full subscription? I don't want to pay for a whole new set. And the app sometimes misses shots too but that's a separate issue. Any tips would be great. I'm starting to think I wasted my money. Lol but not really.
