Kannada keyboard (Mobile)

I just installed the latest update. There is a bug in the app. When a letter is pressed and held, it does not show the consonants and conjunct consonants. If the app is used for the first time, it shows the consonants and conjunct consonants. But if I try for the second time, it does not show them anymore.

This is the only app I could find, which both allows integration into the system as well as being free. Thanks for this.

First of all thanks to app developer for this free Kannada app for iOS devices. I tried it but find it very hard to compose a sentence. Would love to see further updates.
