Multiple issues relating to tracking runs - hoping for advice.

I have been doing the runna 10k plan and feel the plan itself is really good for building up, however, I have some issues with some of the insights from the app and my watch. For context I use the strava app on my samsung watch and link it.

1. If I am doing an interval or hill run, I will record the full time I am running, including warmup and cool down, however the runna app insights always says "Well done on your run, don't feel bad about not completing all the reps/paces" but every time I have completed then at least as quickly as required. Is there something I need to do differently? For example, should I be pausing the workout when im in the walking period between kms?

2. While I'm running my watch always shows my current pace as slower than I am, I think it shows the average pace since I started the run rather than what I'm running at that time, it makes pacing hard, trying to calculate it as I'm running.

Has anyone else experienced these, and any advice on how to get round it? Thanks in advance!
