"Sign in to Complete Purchase" message after updating to Apple Watch OS 6.0

I'm getting the message "Sign in to Complete Purchase" every time on my Apple Watch after installing OS 6. Also, it asks me to login to an old Apple ID that I don't use anymore...


The message keeps popping up on my wrist 4-5 times and then it goes out for a while.


Reeeeeeeally annoying!

OK. Here is the fix that worked for me!


  1. Open your Apple Watch app on your phone and go to “My Watch”
  2. Go to Settings/General & turn off Automatic App Install.
  3. Now go back to “My Watch” and scroll to the bottom to see “Available Apps”.
  4. Any apps you see that are trying to install are the culprits causing the notifications!
  5. Delete those apps from your phone, and if necessary reinstall them with your Apple ID used currently.
  6. Turn Automatic App Install back on if necessary.


You now wont receive any more of those annoying notifications!

Understood - Here's what you can do: Go to the watch app on your phone and disable automatic updates. Now, you'll see which specific updates have failed (i.e. that are associated with an older Apple ID) , so you can delete/remove them and re-download them associated to current Apple ID. Not fun, I know, but it's a fix that works. LMK how you get on?

I have the same issue and it is so bad that I'm considering returning my watch. The message keeps popping up, dozens of times each day, each time I have to dismiss it 4 times.


I changed accounts a few years ago and some of my apps (apparently) were "purchased" (even though I paid no money) with the old account which I can no longer access. I don't know the account password and have no way to know which apps are linked to it. Instructions that I have found on Google do not solve the problem--I can't switch off auto app update as it immediately reverts.


This is part of a larger problem Apple has with passwords. Half the time it does not recognize my password and if (heaven forbid) it doesn't recognize it 3 times in a row, you have to reset the password with a new one--DIFFERENT from your original one. This makes it incredibly difficult to remember as it is a new password every other week.


Apple keeps suggesting I move to 2-factor authentication. My apple account is a major pain to get into with one factor--I can only imagine that if I enabled 2-factor authentication that my life would become exponentially more frustrating.

Very annoying indeed.


The instructions by Watersideguy didn't work for me. So I deleted almost all of my apps; I figured out how to delete the old account--not trivial and full of "warning! warning! warning!" messages and emails; and I was eventually able to turn off all automatic updating. I'm not sure which of the above (hours of work!) did it, but finally I've regained control of my watch.


Apple security is beyond frustrating to me. While no longer being asked to enter my password hundreds of time each day, I'm still asked daily. When it happens, I break out in a sweat, hoping hoping hoping to get past the trial. I s-l-o-w-l-y, o-n-e c-h-a-r-a-c-t-e-r a-t a t-i-m-e enter my password and still usually mess up. Then it asks me for the make of my first car. I enter "VW" and am told that is incorrect--cars must have more than two characters so I enter "volkswagon" (trying to remember if it is an "o" or an "e") after which it asks me the name of the street I grew up on. If I mess up three times in a row (which happens frequently because I'm not a good typist on a cell phone and they don't show the characters after you type them), then I have to reset my password. And of course they don't let me reuse any one that I have used previously.


I keep getting prompted to go to two-factor authentication when I can't even get into my phone with one-factor. I can only imagine what would happen if I went to two-factor authentication--I suspect my phone would become an inaccessible brick.


If Apple (or any other company) can figure out how to NEVER AGAIN ask me for a password, I will be their customer for life.
