Describe the bug

I had a red tile in the app. Today it is gone, because the risk calculation only considers 10 days now.
But I expect this contacts still to be shown in the journal because there are still 15 days shown.

Steps to reproduce the issue

1. Have a contact
2. Wait 11 days
3. See the contact journal

Expected behaviour

The entry at e.g. Tuesday 2 weeks ago was there and should stay there as long as the days is shown in the journal.

• It would probably make sense to implement Reduce contact journal amount of days stored to 10 cwa-wishlist#815 so that the period of consideration for risk checks and for the Contact Journal are the same.
• This should be standardized across both Android and iOS, so I suggest the moderators movie this issue to the cwa-documentation issue list.

Thanks. I looked for the first one, but in the wrong repositories.😉

I used the search field in the top left of GitHub and typed org:corona-warn-app is:issue is:open journal in:title to find it. It's quite tricky sometimes with all the different repositories.

I can't reproduce this issue, High risk is not removed from contact diary after 11 days, please provide error log if you can re-produce it ?
see recording:

risk.mp4

@mlenkeit Did the device perform a new risk check on 23/09/2022 (i.e. do you still see the red encounter on the "Status" tab or only the failed card)?

@Ein-Tim I think you mean me.It did not. I see failed risk card. do you think future calculations matter in this occasion?. as far as I know when high risk is reported from ENS or ChecksIns it is saved in contact diary database independently from risk calculation

[Ein-Tim]

@mtwalli I guess if the app would turn green again the contact would also be removed from the contact journal, maybe you could test that?

Because AFAIK the current implementation, at least under iOS, is that risk encounters are removed from the contact journal after they are not displayed anymore on the "Status" tab.

[DerVogel2020]

@mtwalli started error logging and will check in a few days.

[DerVogel2020]

@mtwalli this still occurs.
The error log is ID 6A10B254EB600F352CBE

I can provide a screenshot from yesterday and from today, where the entry of 9.9.2022 is gone.

@DerVogel2020 You are right that the risk disappears from contact journal after 10 days (atm). There was an intended change in v2.20 to restrict exposure history to specific age (configurable from AppConfig) at the moment it is 10 days.
Change in the app meant:

for ENF, when obtaining Exposure Windows, they are filtered by age against a parameter from the app config before any other processing (risk calculation, PPA, contact journal, etc.)
for event registration, check-ins are filtered by age against a parameter from the app config.

Therefore it is not a bug, however I see that this can be still confusing to the user and Contact Journal might be restricted to configurable age too.
Fortunately there is a swishlist request for that corona-warn-app/cwa-wishlist#815

As I mentioned earlier, this is working as designed and no plan to change it in the future.
