No transfer of shopping cart contents

Hello,

Magento 2.2.2
Henhed_Piwik
Matomo 3.3.0

Tracking works until the shopping cart, but the checkout does not transfer the data and the shopping cart is empty.
It’s not always like that, sometimes it works.
Does anyone know the problem and has a solution?

Best regards
Klaus

Hi,

I am not sure if this is an issue with Matomo or the integration.
I saw that you have already opened an issue here:

The sum is fixed, but where is the quantity?
