Since the update to 9.3 my clone pages do not work
I have products per country, in the page I only have one model, the product model
The country is filled from the original product
If you try to save
If I open the country selector and select the country and save again It returns Invalid reference Id 
It seems to be trying to clone the Country__c object…
As odd as this may sound, try switching themes back and forth. I find, strangely enough, that Classic simply doesn’t do cloning on 9.3, but the others do once you switched the themes up.
… tested with the new lightning theme and the modern theme… and it works now…
should I start changing my classic theme pages to other ones to avoid things like this?
Dunno really. I’ve only had the one issue that relates to this.
