Last week Microsoft released the first update for the Remote Desktop Client for iOS in a year. Version 10.0.0 includes Windows Virtual Desktop (WVD) support, improved external keyboard support, dark and light themes, a new UI, and more. Microsoft quickly pulled the app from Apple’s App Store with no explanation. The only reported issue with this new version that BleepingComputer could find was a Japanese input problem that still exists and with this release, third-party software keyboards no longer work.
