When adding a member to a group, the "Add" button is so close to the keyboard select icon, that it is almost impossible to click.
Careful taps from the side of the screen occasionally get through, but before you manage to do that, you have clicked the keyboard selector icon 10 times, which cancels the Add action.
Also the cancel button seems to be on some OS navigation bar icon.
The keyboard selector icon only appears if you search for someone using the keyboard and do not close the keyboard before clicking on a name.
