I'm using 5.5 beta with Tizen target. 1. Development build text shows in the right hand corner of the app running in emulator even if development build isn't checked. 2. Fonts don't show on the device. 3. I'm able to build and push no problem but after awhile I can't and I keep getting the error: key[error] val error message: Signature Verification Failed Tried it twice on 2 different machines. Restoring code based back to a time when it work doesn't help. Any suggestions?
