Sketches and shapes missing after workspace loaded

Have anyone experience some of your sketches and shapes went missing after your workspace is loaded? I am not sure what happened but everything was fine up until yesterday. Today when I tried to load my workspace, first it took forever to load the workspace, which doesn’t happen before, and when it finally loaded, several of my sketches and shapes went missing. The workspace is also froze and I can’t seems to do anything with it. I have restarted the app several times including restart my iPad Pro but the issue seems to be persisted. Anyone else encountered this?


can you send us the workspace ( or upload it here. We’d like to have a look to understand what could be the problem.
