    iMessages in iCloud is delayed again? Honestly I don’t understand the feature anyway, but they hyped it up and then don’t release it which is weird.

    Anyway I don’t see any major updates with this iOS 11.3 release, but I do wonder if anyone has problems with it or if it has been flawless so far? I have learned to hold back on my software updates and let other people sort out the trouble… maybe I will update this weekend when I have spare time to troubleshoot iPhone if it has a problem.

    • Michael says:

      the iMessages was in the 11.3 beta 6 release 15E216A. But I’m hearing it’s not in GM. The phone won’t do an OTA update. Only way to get GM is through IPSW. But not sure I should do this. iMessage for iCloud is working on iPhone, iPad, MacBook Air, and my iMac. But they did not release GM for MacOS 10.13.4 Beta V7 (17E197A).

  2. katbel says:

    the new update requires iTunes 12.7.3
    that I hated. Still with 12.6.3. And I don’t like to update directly from devices
    Any workaround?

    • vdiv says:

      Could create a MacOS VM with the new iTunes and use that to upgrade, or just run the upgrade on the device itself, but this is only delaying the inevitable.

    I”m with you Katbel, I’m on 12.6.3 also. I have capped satellite service and with four devices in the household I’d be out of data in a week with all the updates. Hopefully Apple wakes up.

    • imacconvert says:

      Only person I have seen make a point about data useage other than me.
      Pet hate, Apple supply an update and never show the amount of data download. its quite arrogant to assume they only have US customers and live in Silicon valley or equivalent with fibre optic speeds and unlimited packages.
      If only. Satellite is good, but it costs.

      • Dun says:

        You shouldn’t be angry at apple. You should be angry at your government that doesn’t have decent infrastructure. Since you don’t have decent internet infrastructure you are forced to use the same technology they use in Antarctica.

        Also if your telecom companies were not an oligopoly, you might have been able to get massive LTE datacaps like most of the world. I pay $35 for 1terabyte of blazing fast, low latency LTE! and I live in a third world country.

        • Paul says:

          There is a download size indicator next to the iOS 11.3 software update package in the Settings, the size varies per device, but should be between 500mb and 2GB depending on what hardware it’s being installed onto and what is the prior version.

        • Steve Ac says:

          thanks for the link, i’m still using 12.6.3, but even if you update to 11.3 outside of iTunes, I believe that any device which uses iOS 11.3 will not be able to sync with iTunes 12.6.3, and thus a central store for apps would be lost.

  5. JB says:

    So my biggest issue (bug) was not fixed in this new iOS release. I’m referring to the bug in which my iPhone X stops responding to anything I type in (TXT, eMail, URL entry, etc.) for 7-10 seconds and then types out whatever I typed 7-10 seconds earlier, and then the cycle repeats.

    The only temporary solutions are:
    -Restart the iPhone (not good)
    -Open app switcher and close all other apps (also not fun)

    I thought it might be an app but I eventually verified that no particular app or app combination is causing it.

    I know other people have the same issue, but not everyone. So far, Apple Support has no solution that I am aware of. This is a big PIA.

    OK, rant finished. Thanks.

    JB
