Describe the bug

1. An Event with start and end date is created on an iPhone
2. The qr code gets scanned by iPhones and Androids:
   The iPhones show the Enddate and the auto checkout is probably than
   The Androids don't see the enddate and auto checkout after 15mins.

Steps to reproduce the issue

Expected behaviour

The android devices should checkout when the enddate has passed.

Possible Fix

Additional context

I don't know what's the problem:

• The creation device creates a corrupted qrcode
• The android device CWA has a bug
• Old App versions where used

I don't think the iPhone will checkout at the end time but also after 15 min if you don't change the typical length of stay. Try it.

It's not really clear to me for what the start- and end time is actually used: corona-warn-app/cwa-app-android#2950 (comment)

[jucktnich]

I don't know how it exactly is, but the androids checked out, while the iPhones didn't

[Ein-Tim]

@jucktnich

Are you sure that the iPhones weren't set to another check out time?

[jucktnich]

Not completely sure but I think so

[Ein-Tim]

@jucktnich

Okay... Anyways, as I wrote here, I can't reproduce that iOS uses the end time of an event for check out.

I suggest to close this issue in favour of #657.
