Photos shared library no loner syncing
My wife and I share both of our personal photo libraries to have one shared photo library.
This has been working normally for the last few months but as of about 6 days ago it has stopped working entirely.
For example, I have taken photos on my iphone but these do not appear in the shared library on my wife's phone - and vice versa - she takes photos on her phone and they no longer show on the shared library on my phone.
We can still see previous photos from each others libraries and they have the shared library icon on them.
I have checked all the icloud settings and everything looks normal. We have plenty of storage available (1.1 used of 2TB)
I would appreciate any suggestions as to how to get this working again.
