I have 3 main questions about myViewBoard functions. Could you guys please help me find the answers?
1/ How long will QR code available when it created?
- If QR code is saved in somewhere, how could we find the folder or the way to get it back when we close it suddenly or something else?
- If QR code is in temp memory when it created, how long will it available when we close QR code tab or even exit the application.
2/ Why are our strokes always stay in front of pictures and could not modify or layer it?
