Graph squashed

When I open pvoutput on my phone the graph is squashed.
To fix this I have to turn to landscape, refresh where it then goes to full screen then I can turn the phone back to portrait and it is back to how is meant to be.

It’s been happening for about 4 months give or take. I just hadn’t got around to reporting the issue. I’ve never had this issue before.

There hasn’t been any updates to the graphing that would change how things are displayed on mobile.

I have also noticed it seems to happen only on the live day where it’s not actually a full day yet.
If I scroll to a previous day it displays the graph fine and go back is still squashed.
This is the squashed view, then landscape, refresh and re-portrait view
