after a long investigation, with many solutions in the marketplace.
none can solve this problem.
it seems to me that it is time for acf gallery to evolve a little bit or have an way to allow us to select a basic uploader option for gallery or an easier way presentable for frontend forms.
maybe another special add-on gallery ?
for suscribers and users
(for admin the wp uploader is perfect )
like millions of people I use acf gallery connected to the elementor gallery widget.
I hope to receive a positive opinion on the subject
thank you
