[1]Apple Investigating Unresponsive iPad Pros -- A number of iPad Pro users have reported that, after charging, their tablets stop responding and show only a black screen. Apple says that it's investigating the issue, but in the meantime the company recommends forcing a restart if your iPad Pro is locked up, which you can do by holding the Sleep/Wake and Home buttons until you see an Apple logo. [2]Read/post comments [3]Yahoo Mail Blocking Some AdBlock Plus Users -- The war between advertisers and ad blockers has escalated. Yahoo Mail is reportedly blocking some users of the AdBlock Plus browser extension, displaying the following error message: 'Uh oh'¦ We are unable to display Yahoo Mail. Please disable Ad Blocker to continue using Yahoo Mail.' For those who don't wish to disable AdBlock Plus, a workaround is to change Yahoo Mail's view from Full Featured to Basic, although that may result in an unsatisfactory user experience. [4]Read/post comments [5]The Wirecutter's Guide to Prepaid Cellular Plans -- The prepaid cellular landscape is dense and complex, but Rob Pegoraro has written a guide for The Wirecutter that cuts through the confusion. Unlike most of The Wirecutter's guides, this one doesn't present a single best choice, but rather a variety of recommendations depending on your needs.
