To mitigate increased congestion conditions in some parts of China we're pushing an updated version of our Shadowscale app for iPhone and iPad. The updated version is more aggressive in dealing with poor network conditions.
Please look out for Shadowscale version 1.8.3.
Unfortunately, due to COVID19, Apple is slower than usual when it comes to approving apps. Where this normally takes 24-48 hours, we now expect Apple to need a week, possible longer, to approve our updated app.
