Sometimes some settings are cached. Might take some time to reflect on the POS.
If it is a test system, we try the following based on urgency.
1. Log off>> Close POS application>> Login.
2. Restart CSU from LCS if it is Cloud Hosted or do an IIS reset if it is Self-hosted.
3. Reactivate the POS (this works most of the time).
4. If nothing works, have a good sleep and come back the next day. It will definitely work.
Note: Please try to maintain a single thread for the same issue/discussion in the forum.
