If you have installed iOS 14 on your iPhone and you have changed any of the default Apps that are configured, such as Chrome instead of Safari to open a link to a web page, do not think about running out of battery or restarting the iPhone, Because if you do, those changes will be lost and you will have to configure the Apps that you want to open by default, once again.
iOS 14 is the first version of the iPhone operating system that allows us to choose which Apps we want to open by default, and after several months of testing and with this well-reported bug for a long time, Apple has decided to publish the final version sooner than anyone expected. . This bug was known, but it has not been an impediment to launch the App, with one of its novelties half cooked.
The next minor update to iOS 14 will likely fix this problem, now that it has risen to the public eye and a reboot is known to re-set Safari as the default web browser, or Mail as the mail client.
Apple has confirmed the bug to CNet.
