Variation Quantity Does Not Change
Expected behavior
When the selected variation changes, the quantity should update to the effective minimum of the new variation.
Check the variation values
Confirm that each variation is saved with the intended Min, Max and Step configuration.
Check frontend conflicts
If the quantity remains unchanged, temporarily test with any theme quantity enhancement or other quantity-management plugin disabled. Another script may be replacing the WooCommerce quantity field after Deviking MinMaxStep updates it.
Clear cached assets
After updating the plugin, clear page cache, optimization cache and browser cache before testing JavaScript behavior again.
