Losing daily streaks when switching between Android app and website

So the first two times this happened I thought I was either imagining it or had somehow accidentally missed a day. But there is no question in mind I used the Android app yesterday to ensure I hit my daily goal and the app confirmed my streak had continued another day. Today I logged into the web version, and sure enough, it had completely lost track of my streak again. Has anyone else had this problem and if so what can I do about it, because I should have a streak up in the high 60s by now…
