how to fix apps auto updating issue even when auto update turn off on google play store | how to turn off apps updating automatically?

It is important to see which apps are updating ...on inspection i saw that my apps were getting updated from galaxy store....so turning off auto update apps just from play store won't help , i needed to do this from settings of galaxy store as well

So , first figure out where the apps belong - play store or galaxy store and better is to turn off auto update from both places
