I soldered a trinket m0 for my friend's switch and when vol+ strap is soldered the vol+ button itself is acting as a vol-, vol- isn't functional and when I press launch without a microsd card inserted the "couldn't init microsd card" error message is being displayed all across the screen and softlocks the device. I didn't short anything while soldering, I even tried to solder the strap to the ribbon with the buttons instead the make sure it isn't my soldering and setup the trinket from scratch. Can anyone help? I'm clueless.
