Hello, in the last few days we have been working with Fireblocks Support to enable trading via the Provider Network in our Sandbox account. Support was able to activate the feature for our Sandbox account, and we are now able to list providers via the API (previously we only got 403 forbidden responses), which currently are just `UNISWAP_CLASSIC` and `UNISWAPX`.

To test the functionality I tried doing a swap via the UI. In the UI, I am able to get a quote and initiate a trade, however invariably the swap transactions fail with Internal Server error. Example FB txn IDs are `551a8556-0243-47aa-922d-3f4fe0399a6d` and `5b190200-663c-4f0b-b6a3-eebe1394e605`.

I mentioned these failed transactions to FB Support, and they asked if we have set up the TAP policies. However, since it is a Sandbox environment, we cannot update the TAP policies, since in the UI they are disabled and grayed out in.

First question, did these attempted swap transactions fail because of the needed TAP policies?

Secondly, how can we update the TAP policies to enable trading via Uniswap?

Many thanks!
