Dear friends,
There was recently a technical issue which occurred at the Cologne Digital Sanskrit Dictionaries website which started showing a message that it required a VPN to log on to. The issue was transient and is not present now.
As an alternate to the regular website, a few colleagues here suggested alternates which are available to access dictionary data.
Earlier the app was available only for iOS. In the interim, the android app has also become available on Google Play Store. I am sharing the official alternatives to access Cologne dictionaries.
