Chomp sms notification preview?

[Antmf]

I was using textra and all was working fine. I was getting G my text message previews on my locked screen or home screen but since switching to Chomp I get the alert and vibration and icon in my notification bar but no more previews. How do I get the previews back? I have my settings for phone set to show preview but still nothing. Any help would be appreciated. Thank you.
P. S. By preview I mean it used to pop up in middle of screen. Now I have to pull down notification bar to see it.

Chomp doesn't support it. I already talked to the developers before and it was like they had no idea what I was talking about. Textra last I checked only had previews because it was built in, not because it used the Android framework's preview. I noticed it when Textra's previews were black but my Android previews were white.
