Problems in the use of mac quiver softwar

when mac uses quiver, when it is set to markdown, it is found that the copy-and-paste shortcut key is invalid and can only be copied and pasted with the right mouse button. This failure also causes the picture after screenshot to be unable to be pasted. If the software does not support copy-and-paste shortcuts, you have to give it up. Are there any friends who have the same problem? (other software on my computer is easy to copy and paste.)
