Back in September, Apple increased the cellular download limit for apps to 150MB but for some reason that did not apply to beta apps installed via TestFlight.
The TestFlight app allows testers to install and beta test apps on iOS, tvOS and watchOS devices. Testers must receive an invite directly from a developer first before they can begin testing with TestFlight. Once invited, testers can redeem invitations in TestFlight to install, test, send valuable feedback, and get updates for the beta app.
What's New In This Version:
• This update includes support for Smart Invert Colors and a revised 3D Touch peek view that includes “What to Test”.
• The cellular data limit is now 150MB, increased from 100MB.
• Small bug fixes and other UI improvements were made.
You can download TestFlight from the App Store for free.
