Silent overcharges and forced plan changes in Shopify apps
Existing app users are charged above the agreed or listed price, or moved to paid plans, without notice or consent

What's going wrong
Shopify merchants report that apps charged them more than the price they accepted, or moved them from free use to paid plans without asking. One store owner describes being billed more than double the agreed fee by an upsell app. Another describes a cheaper plan launching while existing customers kept paying the old higher rate for months, and a refund request was refused and redirected to a new plan. The reports come from small store owners and agencies and span several cart, upsell and personalization tools, so the problem is not tied to one vendor. Usage-based and revenue-based plans look most exposed, and billing emails that imply approval add to the confusion. A fix could flag install prompts, plan changes and billing emails that imply a charge, and warn merchants before any money is taken.
