When I use managed pricing link in Polaris web components like this :
<s-button href="https://admin.shopify.com/store/:store_handle/charges/:app_handle/pricing_plans"> Select a plan </s-button>
Clicking the button will open the pricing plan page, but it will auto redirects to the store settings > Apps and sales channel page immediately.

Seems like not related to Polaris web components, accessing the link directly has the same problem too :
I see draft in the URL Is that intended?
Yes, the app handle name includes “draft” and is intended (I have other apps that include this in app handle as well) . Does this affect the behaviour of managed pricing?
I tried using the app client ID in place of app handle, same issue still occur
It looks like the app is named yagi-draft-variant not yagi-variant-draft
Good catch! Thank you 
, sorry I got confused previously
