Hello. I recently posted this warning about developer options.
In the last 5-6 stable versions published by official Instagram, almost all of the developer options consist of numbers. I succeeded to find out which developer option the numbers affect. I also made a file that lists what developer options the numbers turn on/off.
Download developer options (txt-text file):
As you can see in the example below, the number "42962" means "ig_labs_android_edit_profile_grid".
42962 ==> ig_labs_android_edit_profile_grid
So if you enable the "42962" options as shown below, you will enable the developer option "ig_labs_android_edit_profile_grid" corresponding to the number "42962".
Enabling the "ig_labs_android_edit_profile_grid" option turns on pinning posts feature.
After enabling "42962 (ig_labs_android_edit_profile_grid)" you can now pin your posts:
Developer options are created by Instagram and have nothing to do with Aero side. Developer options is a panel that is already inside official Instagram app and is exclusive to own developers/owners of Instagram. All Aero does is make these options accessible to everyone. As you can see, the developer options are removed or encrypted in the official Instagram versions. Almost all developer options have been converted to numbers by Instagram and the file on this page also contains the real names of all numbers.
Download the file on this page, search for the name of the developer feature you want to activate in the relevant file and on/off/edit the numbers corresponding to the relevant developer feature by searching through the developer options.
You can find many developer options here. More may be added in the coming days.
