There is a "New batch job" option in "File" as well

Hope you figure out what works best. I dont make a living using these products, so hiccups like these are fine for me.

I can understand it being frustrating and potentially worth the Adobe subscription when you have a job to get done.

Good luck!

You should just be able to go to File -> Export and then select jpeg and all its properties.

This is different for RAW files. They should open in the develop persona automatically.

Also, other than this slight hiccup, have you been enjoying using affinity?
