@JABirchall the safe transaction service will discontinue the price calculation in 2 weeks https://forum.safe.global/t/important-update-changes-to-token-pricing-in-our-api/4392
This doesn't mean that the webUI will not show any price, the prices are now returned by other sources, if you currently have any issue with the price of the token that you mentions I suggest you open the issue here https://github.com/safe-global/safe-client-gateway
