Thanks for confirming.
Regarding tutorials;
Good news - 1.4.1 release should be available in the App Store and it comes with the fix for tutorials duplicates. From now on each tutorial document have a hardcoded UUID, so when they get generated on multiple devices they still get merged into one single Document. CRDT is beautiful.
Bad news - existing users need to remove old tutorials for the fix to work. Matching old and new tutorials based on title only could cause problems for some users. Sorry.
