Ugly live graph on iPadOS 16.3.1

Recently, my iPad got updated to 16.3.1
Now I have these dash or dash/dot lines on my live graph. The lines on all other graphs (daily/weekly/…) are OK. Same behaviour with Chrome and Safari browsers.
On all other devices (Android phone, windows) it is also OK
Anyone else having this issue too?

For me charts stopped working at all on iPhone & iPad …

This was reported by another user after their ios was recently updated.

It seems pinching / zooming renders it properly.

Unfortunately I don’t have an ios device to test this with, but will try to get hold of one.

Click on the greyed out ‘Generation’ label next to ‘Export’ to enable the series.
