MacBook Pro 2018 no haptic feedback OS Catalina I have a problem with my MacBook Pro 2018. There no haptic feedback on the touchpad. It worked with Catalina well, but only for a few days.
The touchpad works very well with all gestures. There is only no vibration when I klick anything.
What I did:


restart the MacBook
NVRAM reset
SMC reset
I set the MacBook to default configuration and don't logged in with my Apple ID.


Anybody here who has another idea what to do?
For my 2015 MBP, this happened immediately after upgrading to Catalina.

My MBP was no longer under warranty so going to apple wasn't an option.

What worked for me was:

"It just started working again a few days later"

Most of the advice I found elsewhere, and tried, was:


pram reset
power off and leave it off for a while
check for battery swelling 


my battery was swollen a year ago, when it was under warranty, and
Apple replaced a lot of things

send it in under warranty
