Problems updating apps from Google Store

I've just installed Graphene on a new phone. Please can you help me with confusion updating Google Apps?

I have Aurora store in my main user account. It reports 1 update available for "SIM Manager", which doesn't appear in my list of all Apps even when I select "Show system". When I try to update I get an error "Existing package signatures don't match newer version". I have updated another package successfully.

I have sandboxed Google Play Store in a separate user account. When I click to show updates it reports "Something Went Wrong, Please Try Again". I can install apps OK.

Many thanks.

intelligence You should not be updating that.

Great thanks that's useful to know. So in theory I could add SIM Manager to the Aurora "Blacklist", except I can't because it doesn't show up as an installed app. (SIM Manager is com.google.android.euicc which I don't have, but I do have com.google.android.euiccoverlay and a few similar ones).

It's quite confusing: how can an App exist yet not exist? Does anyone else see this or is it only me?

Great thanks matchboxbananasynergy.
OK I found a fix. In Aurora I enabled "Filter Google Apps", and the problem has gone away. I'm very grateful for the very helpful community here welcoming a noob😃.

I'm still seeing problem 2 - sandboxed Google Store "update checking" not working on second user profile (I'm not talking about a work profile). Is this something that ought to work, or am I heading in the wrong direction?

Oggyo Yes that's exactly it many thanks. I also toggled Aurora's settings - Settings | Updates | Extended Updates. I had intended it for apps that I had installed and then frozen because I only used occasionally or they hog background CPU.

Thanks. All 3 apps have permissions for network and sensors, and nothing else.
