Noticed 2 MPT Issuance IDs on top of each other in the screenshot for MPT page

That's because it's a tooltip for the ID - similar to the NFT page

I'm not sure which way is better: the current way of showing scaled amount, or just showed the amount divided by 10^scale (so that on payment and clawback simple page we dont have to click on the token itself to find out about the scale). Other than that, looks good to me.

The failed tests can be fixed when merging latest changes from staging

Personally, I'd rather see the scaled amount instead of having to do the math myself.

@mvadari @pdp2121 One problem with showing the amount divided by 10^scale that is the information of the AssetScale is stored in the MPTokenIssuance object. This means that whenever MPT amount is display, we would need to make an extra call using the ledger_entry API to fetch the MPTokenIssuance object to get the scale.

I think that's fine.

Yes. I would prefer seeing the scaled amount. We are also showing scaled amount in PriceOracles tx.

LGTM. Just left a comment and may be get the linting fixed

Not quite sure why the lint fails, the ones that are failing are the ones that my local linter told me to fix.
