I installed an Anemone theme from Cydia called “iPhone X Theme” to get the dock from the iPhone X on my iPhone 6s, but it didn’t look very good, so I disabled the theme and deleted it, but the dock still didn’t go back to normal. Here’s what it looks like right now. My clock app also got messed up
To fix it, all I did was disable all the themes on anemone, then restart my device. After then, I just reran the jailbreak, and everything went back to normal!
