Starting Android N (7.0) and up, Google has chosen only to allow leaf certificates that expire within 39 months.
First mentioned for chrome in 2015: https://bugs.chromium.org/p/chromium/issues/detail?id=475745
Could you please consider either reducing the lifetime of the root CA to <39months AND / OR allow us to import our own CA like competitors already offer.
We like working with Fiddler but the inability to supply custom CAs easily and not adhering to the above requirement set by Google in Android 7.0 + forces us and many others to having to avoid using Fiddler.
