Why does the data sync keep restarting after a Styku Studio software update?

After a major Styku Studio update, the software may need to re-measure or re-sync a large number of existing scan records. As noted in Styku's documentation, previous scan data may be re-measured to use the latest measurements after an update, but scans and customer profiles are not lost. If your account has thousands of records, the sync counter may appear to reset several times during this process, and the system may be unavailable for new scans for an extended period. This is not normal expected behavior — contact Styku support to have a technician assist you directly.

What you may be seeing

During a post-update sync, Styku Studio displays a counter showing how many records remain to be synced (for example, "syncing 1 of 18,000"). In some cases after a major update, you may notice:

• The counter resets to a higher starting number after making some progress
• The sync has been running for several hours with no sign of finishing
• You are unable to start new scans while the sync is in progress

This behavior can occur when a large update requires existing scan data to be reprocessed or re-synced. Styku stores scan data and customer profile information in two places — on your local computer and on cloud servers — so both locations may be involved in the sync process. Accounts with a high volume of scan records (thousands of scans) are most likely to experience a lengthy sync.

Note: The update process itself can take approximately 10–30 minutes to complete on average. The post-update data sync for large accounts may take considerably longer.

What to do

1. Do not close or restart Styku Studio while the sync is in progress. Interrupting the process may cause further delays.
2. Confirm your internet connection is stable. Styku Studio requires an active internet connection to sync. A dropped or slow connection can cause the sync to stall or restart.
3. Note the current sync count (for example, "syncing 344 of 17,500") so you can report it to support.
4. Contact Styku support to schedule a session with a technical representative. A technician can review your sync status and take steps to resolve the issue.

How to contact support

Because this issue typically requires a technician to investigate directly, the fastest path to resolution is a scheduled support session.

Log in to the Styku Business Portal at styku.com/portal and submit a support ticket using the Need Help? form. A support representative will respond within 1 business day and can schedule a screen-sharing session to assist you.

If this resolves your issue, no further action is needed.

If the problem persists, contact support and include: your Styku Studio software version number, the total number of records shown in the sync counter when it resets, approximately how long the sync has been running, and a screenshot of the sync progress screen.

Applies to: Styku Studio v5 and later, all Styku scanner models, accounts with large numbers of existing scan records
