Apple's Support Community website has been flooded by posts from disgruntled customers who are complaining about the latest update for iPads and iPhones, which they say only served to break the gadgets' software instead of fixing it.
Released on Oct. 21, the iOS 9.1 update included 11 features that were designed to address bugs in the gadgets' system, such as issues with incorrect unread email counts, activation errors and unresponsive Calendar and Game Center apps.
Instead of fixing the bugs, however, Apple product users wrote on the company's official support forum that the update caused the Touch ID across iPads and iPhones to break.
Many of the complaints focus on the Touch ID's inability to recognize the fingerprint of users. Customers pointed out that the system is no longer reliable as fingerprints pressed against the gadgets do not seem to register anymore.
"I'm using an iPhone 6S 64 GB and upgraded to iOS 9.1 a few days ago," user "moniker dan1207" wrote.
"My Touch ID has become very slow or either doesn't work after several attempts, and I need to input my passcode."
Some iPad and iPhone users have even tried to hard reset (holding down both the home and power buttons simultaneously for 10 seconds) their gadgets and complete the factory reset but to no avail.
"The Touch ID was working normally before installing iOS 9.1, then after the restart and after entering low power mode, it stopped working," user "fentium" wrote.
Apple's decision to discontinue granting permission to install the iOS 9.0.2 update within days of launching iOS 9.1 has also prevented affected users to downgrade back to the older version of the software.
The recent issues with iOS 9.1 have once again raised questions regarding the Apple's strategy of rushing update releases.
While it has become a standard practice to release subsequent updates after launching a new product, observers believe Apple should rethink its strategy to avoid running into similar problems with the last year's iOS 8, which is considered to be the buggiest update the company has ever released.
Tech experts also criticize Apple's discontinuance of providing downgrade routes that would have allowed users to switch back to a more usable version of gadgets software in case they experience issues with newer releases.
For the moment, users affected by the iOS 9.1 issues will have to wait for Apple to launch a new software update to fix the bugs.
