Good day,
Thank you for your message.
I understand it’s not possible to reply to support request daily, that is why I waited 3 days before any comment.
Hope in the new update some issues will be solved.
I tested on Ipad 9.7″ 2018 and on old Ipad second generation. Both same issues.
As mentioned already, I replace the grid portfolio with a different plugin.
Regards,
Gerry
