We created a fix (version 2.0.7) as soon as we became aware of the problem, which was released to Apple on the 15th. Apple have to review all changes before they are made publicly available. This usually takes up to 10 days but we have requested it be expedited.
We apologise for the inconvenience and wish to thank every one who has submitted images of the new designs. These have helped us greatly in re-training the Scrabulizer image interpreters.
In the mean time, you can of course still use the manual game entry method of tapping on the board/rack, and using the keyboard to enter the tiles.
Update (19 July): Apple have now approved the new version containing the fix. Version 2.0.7 is now available as a free update in the App Store.
