Home button and some haptics not working after installing battery

Hi, I replaced a battery on my son’s iPhone 7. The install itself was fine, we had no issues getting the battery replaced and everything reassembled. The phone booted up fine, touchID worked, but the home button does not work (nor do the haptics associated with it). But if I try and the touchID doesn’t accept my thumbprint, then the haptics kick in. So the engine is hooked up properly, it is a home button issue.

I’ve seen this in various forums but no great answer to it. The home button is on the part of the phone that we did not touch significantly. All the cables look fine. We looked for small nicks and kinks and couldn’t find anything. Any other ideas?
