iPhone owners in #Russia may be unable to use the digital rouble when it launches on 1 September, Vedomosti reports. The problem is that banks reportedly cannot upload updated versions of their apps to the App Store , which are required to open digital-rouble accounts. “Banks have so far been unable to upload digital-rouble-enabled apps to the App Store because they contain references that directly indicate a connection to Russia’s state financial system ,” bank representatives said.
