Latest Android and unable to time-lapse sending messages with TEXTRA

[Android Central Question]

Latest Android and unable to time-lapse sending messages.
After the latest Android update ( version 9) Samsung Galaxy 9 pressing the plus signs at the left of the message does not produce the bar at the bottom of the phone that offered me the option to time delay sending messages and other categories. If I reboot the phone it appears again but disappears soon.
Any ideas, this function is very useful.

Email the Textra developers at help@textra.me, with the make and model of the phone, the version of Android, the version of Textra and the problem. (Unless you haven't updated Textra yet - try that first. The last update was 4 days ago.)
