Added support for syncing account and group deletions, i.e. these actions are now part of normal syncing. Note that if you are making radical changes to your data, I recommend that you disable syncing altogether, make the changes then set it up again.

Fixed an issue that caused the app to appear slow for a very small number of users.

Added a workaround for an iOS bug that caused PDF reports on the iPhone 7/7+ and iPad Pro 9.7″ to show as black rectangles (instead of the usual graphs).
