Hello,
i am near to become crazy and hope somebody can help me.
We have an Magento 2.2.6. And everytime when we change something inside a product it looks like he erase the complete category cache.
We have tested it with Build-In FPC (Filesystem & Redis) . And also a test on varnish. He make the same.
For example:
We change price for Product x.
Then the indexer is running.
After this all category caches are empty.
Completly removed.
From my understanding Magento should only only remove the affectet categories from cache. But he really erase all.
Hope somebody have an idear.
Thx for help
Sascha
