App is broken. I have the s21ultra. After using the app for a few moments it freezes and lags out. To the point the keyboard stops working anywhere else in the OS until the app is force closed. Whether you do it manually or the OS does so because the app becomes nonresponsive. Cannot do anything with typing or the app freaks out. Browsing for a while slows to a crawl while loading causing the app to force close there as well.
