The Jira integration is great and very valuable and one of the factors we used in deciding on our tools. One thing that is strangely missing is Story Points for Jira stories. We like use the miro board for story creating and refinement. Then we take it to the next level and size. Once sized we currently need to link to the item directly to enter the size. This takes us out of Miro and if we have that we may just switch to one of the online planning poker tools and work in Jira. Would really like this one field and it would take the integration from 4 to 5 stars!

I could be wrong, but I think this feature exists already… as long as you’ve configured your cards to include story points (or whatever jira field you use to record estimations) you should be able to then modify it when you open the Miro quick view
Hope that helps (unless I’ve misunderstood what you are after!)
