I installed a self-signed certificate on my phone today and now I occasionally get a notification that ever so kindly reminds me that my network may be monitored by a third party, unbeknownst to me. (The horror!) There are all kinds of instructions for fixing this in KitKat, but they are not applicable to Lollipop (5.1)--the directory /data/misc/keychain/cacerts-added doesn't exist. I cannot find a guide ANYWHERE for fixing this on Lollipop. How can I disable the notification on 5.1?
