Unfortunately I can upload a video here, but for example when trying to buy communication credits one of the last steps is selecting auto-recharge option which you cannot select when using edge dev. When using edge stable you can.
This also happens when you purchase a license in admin center and it gives you the option to apply that license to all unlicensed users. With dev, you cannot untick that box. With edge stable you can.
I'm happy to send the video demonstrating this problem to dev team. Please PM me.
