iZettle Reader Connection to Tills – Common Issues & Fixes
When connecting an iZettle reader to a Till, there are two common issues that may occur. Please follow the guidance below to identify and resolve them.
1. “Session Timed Out” Error (Safari Access Required)
Issue
When enabling iZettle payment settings, a configuration window attempts to open via Safari.
If Safari is disabled or not installed on the tablet, the system displays a “Your session has timed out” error.
⚠️ This often requires temporary admin access from our team.
Resolution
Log in to JAMF.
Update Restrictions to allow the site to access Safari.
In the Apps section, add Safari as an allowed app.
This will install Safari on the tablet.
Important Note
The site does not need to actively use Safari.
Safari simply needs to be installed so the Good Till app can complete the configuration process.
2. “Not the Owner” Error (Organisation Owner Login Required)
Issue
After resolving the Safari issue, you may see the error:
“You are not the owner of this Good Till organisation, therefore you can’t add the reader.”
This occurs because only organisation owners (set as sysadmin) can add an iZettle reader.
Resolution
On the affected till (e.g. Till 1), fully log out of the SumUp app.
Log back in using the organisation owner (sysadmin) credentials
(subdomain username and password).Navigate to:
Settings icon → Payment Types → iZettle → SettingsAdd the payment item / iZettle reader.
Log out of the sysadmin account.
Log back in as the normal till user (e.g. “Till 1”).
Result
The connected iZettle account will now be available for use on the till.
