App remains blank when opening in Qlik Sense Client-Managed Mobile-app on iphone

kristien — Fri, 11 Oct 2024 13:45:43 GMT

- Qlik Sense Management Console on Windows is in version May 2024.

- The latest version of Qlik Sense Client-Managed Mobile-app is installed on an iphone 11 iOs 16.1.2

When using the Mobile-app on the iphone, and opening the stream, the Qlik app is visible, but when trying to open it, it is searching for a while, and after that it remains empty - nothing to see.

When the same user opens the Qlik app in a browser on a laptop, she has no problems.

I have published another small Qlik app ont the stream with very little data, assuming that it could be a memory issue, but the same here, nothing to see if she opens it on her mobile app.

I've also changed the Keep-alive timeout to 300 in the Proxy config of the QMC, but that didn't help either.

The user has also switched of/on her iphone.

Before it worked well but she had an older version of the mobile app. I have done an upgrade of the Qlik Sense server. They came from an old version. After the upgrade she couldn't connect anymore with her mobile app, so I have advised her to install the latest version of the app, what she did. And now, she has this probleme

What could be the cause of this problem? What steps can I do in trying to identify the cause of this problem?

Kind regards,

Kristien

The user does not get any error messages on her device.

I have re-analysed the logs she sent me last week, and I see this error. Can it be the cause? If yes, what is to change?

The user with the problem sent me a screenshot of her Mobile App. There are 2 Qlik apps but they have a different icon. What is the meaning (difference) of the green icon int the upper right corner of the app tile?

Hi,

I have a customer with this exact issue. After patching May 2024 the mobile client will show apps as a blank screen and no visible errors.

It worked in May 2024 prior to the patch (uncertain if it is patch 10 or 11).

Hi,

we have the same problems. After patching our system to version Qlik Sense May 2024 Patch 11 the Qlik Sense Client-Managed Mobile-App (version 1.29.1) shows a white blank screen when opening an app.

Best regards.

Hi,

The user installed manually on her iPhone OS version 17.7, and that did it! Problem gone!

Kind regards

Hi,

We have the same situation, but the iOS update did not help (version 18.1.1), still white window after opening the app in online mode. The offline version works fine.

Qlik Sense May 2024 Patch 11 / Mobile App 1.29.1

Test completed successfully – it appears that this is not the cause. This article describes a situation where applications are not displayed in the hub. However, in our case, applications are displayed in the hub, but a white background appears after clicking on them.

Same here.

In my case, updating to QS November 2024 Patch 2 resolved the issue.

We have the same issue at one of our customers. They are currently working on QS May 2024 Patch 11.
Reports are showing in the mobile hub, but opening leaves a blank page.

Any feedback from Qlik yet?

Wir waren ebenfalls auf QS Mai 2024 Patch 11 und sind auf Nov 2024 Patch 2 gegangen. Problem hat sich bei uns dadurch ebenfalls gelöst.
