You closed your rates in your Channel manager or directly in the OTA but they keep reopening?
This is because the connection works from Mews towards the Channel manager towards the OTA, and not the other way around. The restrictions are not being sent back to Mews and therefore Mews will always override them whenever a new update is sent to the Channel manager.
The best solution would be to always manage the restrictions directly from Mews so that your online and offline sales are synchronized.
However, if you want to manage your restrictions directly in the Channel manager, you can disable the updates from Mews so they are not reopened again.
To do that, navigate to Main Menu > Marketplace > My subscriptions > YourChannelManager > Settings > Enabled operations.
Deselect the option
Upload restrictions and Mews will no longer send restriction updates to your Channel Manager. You can use the Notes field and leave a note for your colleagues so they do not enable the restrictions.
