Yeah thats tough. I hate when they do that. The beauty is, it doesnt matter. Usually I just drop a mid number and agile seems to give the flexibility to change that as you identify the true scope of work. Do what you can in the sprint, but eventually update the points to match or break it up and adjust points best you can at that point. Given I haven’t been doing agile long, so I could be missunderstanding how it should work.
