Garage door only opening halfway

My garage door only opens halfway and then stops using this app had the unit for about 2 years works fine up until now tried unplugging the unit replugging it in un uninstalled app reinstalled it , it’s weird that I would start doing this not sure what to do??

This usually happens when the door status is not detected correctly. Please make sure the sensor is working correctly. Close the door with the wall button and confirm that the app reports the door as closed. If it is not reported as closed the laser may be out of the alignment.
