What happened
Inventory visibility and a working recipient link answer different questions. A public profile does not necessarily mean every inventory setting is public, and a visible inventory does not prove that a particular item can be traded. Start with the information the feature actually needs. Making every account detail public because one inventory viewer failed unnecessarily broadens the change and makes the original issue harder to isolate.
What to check
Open privacy settings from your own Steam profile and find the separate inventory setting. Read the current choice before changing it. Determine who needs to view the inventory for the task, then adjust only the relevant setting if you deliberately want that visibility. Revisit the inventory from the appropriate viewer. Check the saved trade address separately; do not treat a visibility change as a positive link verification.
Worked example
For example, your profile biography is public, but another viewer cannot inspect your skins. Changing the general profile heading does not explain the inventory-specific setting. Alternatively, the viewer sees all cards except an item you expected: that may require checking the item record rather than opening more profile details. Describe whether the issue affects the whole inventory or one particular item.
Result and next step
Resolution means the intended viewer sees the information required, with link status documented independently. Record the viewer context and any item-specific message before contacting support. Public visibility is not a promise of tradability, marketability, delivery stock, or account eligibility. Read Steam trading guidance for the distinction, and CASECS2 operation guidance for the difference between an on-site inventory record and an actual Steam transfer.
