Keyboard Disappears

[Android Central Question]

After upgrading to Oreo, a about a month ago, my keyboard disappears when using a variety of apps. It can be my texting app, which is Textra, when using Chrome, or even Facebook and Facebook messaging. I've cleared cache and reset the keyboard, installed and tried to use Google keyboard, but to no avail. It happens sporadically but 1-4 times a day resulting in having to restart the phone each time. Any assistance on fixing this issue would be appreciated. I'm on an unlocked Samsung S7.
