After upgrading to v2 last week (YES!!), I've only encountered a single issue (which is amazing!).
I sometimes call $tbl.processing(true) based on certain events. This call no longer works in v2, and I receive the following error:
Uncaught TypeError: Cannot read properties of undefined (reading '_fnProcessingDisplay')
Anything I can do to restore this functionality? From what I've read, this is part of DT.net 2 as well.
