Missing Jetpack stats

Hi!

I went on to my website to check my stats and it seems that jetpack was disconnected. I re-connected it, but now I have missing stats from 30th April – 19th June. This coincided with a web developer editing the site – but I have asked them and they said they didn’t do anything to disconnect the jetpack? It would be great to get this stats back as it is when my project launched our new materials so we want to see the impact. Any help would be very much appreciated!
