When using the TTMSFMXRichEditor on my Samsung S21+ and I use voice input and after the text is applied, the caret is left at the beginning of the text rather than at the end. So if I were to dictate additional words or sentences, it gets added to the beginning rather than at the end.
It does not accept swipe keyboard input (standard Samsung keyboard) very well. It tends to add it only when I start a second swipe or a tap of the kbd. And when swiping it does not always get the word at all, just a space or a single char. Very odd behavior.
