it's been a long time I worked on an app to be run on an iPad, so I forgot a few things.
How can I send a an app - .fmp12 file - to an iPad ? File size is 64 M, meaning no way to use an email. Even if it was smaller than 10 M, how do I move it to the right place ? The iPad runs on 16.1.1. I used the File app, and couldn't even find the sample file.
I must add that I develop in a Windows environment. I connected the iPad to my computer, but the iPad only exposes pictures.
There should be several ways to do this. One is: Visit icloud.com and sign in with the Apple ID used on the iPad. Navigate to iCloud Drive. Then you can upload a file by dragging it onto the browser window. After that you are able to access the file on the iPad.
Newer iPads support usb-sticks as well, so this could be the easiest way. Not every usb-stick will work on any newer iPad - I got a customer (windows) where I found one single stick that worked with their iPad ('normal' ipad 2022, not air, not pro, lightning connector with an adapter)
