A bug was discovered, when I click on the Save button, the save button becomes inactive and goes into endless saving and everything that has been done is not saved to the server, all the work is wasted. This happens when the Internet connection is unstable. In version 3.8 of SPPageBuilder there was no such problem. If for some reason the page was not saved, the script tries to save again or returns the button to the active state, so that after a while it will be possible to click on it again and save the page when the connection with the server stabilizes. Please pass this message on to the developers because it is a very important message and fix this. Thank you! Screenshot: https://prnt.sc/rtu61EhAVn3Z
