Bug description
After I updated to signal version 4.74.3 the bottom back button and the "+" button (to add pictures to a text) no longer work.
Steps to reproduce
- downloaded the 4.74.3 update
- open a message in Signal
- clicked the bottom back button (see image below). The button just lights up showing I have clicked it, but nothing happens.
- click on the "+" icon (see image below) to attempt to add an image to a message. This button no longer does anything after clicking it.
Actual result:
- bottom back button lights up, reacting to the button press, but does not take me back to the main message window. It stays in the same chat window.
- the "+" icon does not open a add media window as it previously did. If you click on this icon while the keyboard is up, it removes the keyboard
Expected result:
- on previous versions of the app, while in the conversation window, clicking the bottom back button takes me back to my main messages screen
- on previous versions of the app when I click on the "+" button I was able to add an image/saved media to the chat
