# I am unable to enable call blocking on iOS

From our observation, iOS users may have trouble enabling their call blocking & identification extension for ScamShield on certain iOS versions. Before you report the issue, please ensure you have carried out the following steps:

* Updated the ScamShield app version to the latest available version on [iOS App Store](https://apps.apple.com/sg/app/scamshield/id1497144087) (**ver 4.0.1-1**).
* Tried to re-enable the call blocking setting (even if you have the latest version).
* Exited and restarted the ScamShield app.<br>

Our team is working on issuing a permanent fix for the call blocking permission issue and we will be rolling out this fix over the next few weeks. \

If you have submitted feedback, we will be in touch with you as soon as a fix is rolled out.
