I was using Indic keyboard. It said to upgrade to gboard. When i use gboard there is no taminglish words as in indic keyboard. I prefer to stick to indic keyboard but it doesn't show suggestions when typing in search bar. Do add indic languages user dictionary in the gboard app. After update : checked whether there is a tanglish user dictionary or tanglish words available. Only very few words. And the Indic keyboard was stopped. I type mostly by glide typing.
