Looker StudioでGA4だけ、画面表示とPDFダウンロード結果が一致しない現象について

Looker Studioで、複数アカウントをデータコントロールで切り替えてレポートを見ています。

現在発生している現象は以下です。

  • 管理画面上では、選択したGA4アカウントの数値が正しく表示される

  • しかし PDFでダウンロードすると、GA4だけデータソースの既定アカウントの数値で出力される

  • 特定の指標だけではなく、GA4の数値が全体的にすべて既定データソース側の値になる

  • 一方で、Search Console（サチコ）は管理画面表示もPDF出力も正常で、選択したアカウントの内容がそのまま出力される

補足です。

  • 今月中旬までは正常に使えていました

  • 昨日から急にこの現象が起きています

  • どのGA4アカウントを選んでも、画面上では反映されるが、DLすると既定データソースの数値に戻る状態です

  • レポートの版を戻してみましたが改善しませんでした

同じような症状が出た方はいらっしゃいますか？
また、GA4だけPDF出力時に既定データソースへ戻ってしまう原因や回避策をご存じでしたら教えていただきたいです。

We use a data control in Looker Studio to switch between multiple accounts and view reports.

The issue we are currently experiencing is as follows:

In the report view, the values for the selected GA4 account are displayed correctly.

However, when we download the report as a PDF, only the GA4 data is exported using the default account set in the data source.

This is not limited to specific metrics. All GA4 values revert to those of the default data source account.

As evidence, Search Console data behaves normally. Both the on-screen display and the PDF output correctly reflect the selected account.

This issue started suddenly yesterday.

Until the middle of this month, everything was working normally.

No matter which GA4 account we select, the values display correctly on screen, but when we download the report, they revert to the default data source account.

We also tried restoring a previous version of the report, but the issue did not improve.

We would also appreciate any insights into the possible cause of this issue, where only GA4 reverts to the default data source during PDF export, as well as any possible workarounds.

We are still experiencing this issue.

It’s made our reporting very difficult, as we export dozens of reports using different data sources from a single Looker report.

I’m having the same issue as well.
Since there doesn’t seem to be a direct way to contact support, I’ve been struggling to report this problem.
I also asked the same question in the Analytics Help Community, but unfortunately I wasn’t able to get any helpful information there either.
I understand that Googlers are active in this community, so I’m hoping this reaches someone who can investigate it.

It’s really frustrating that there’s no direct way to contact support :disappointed_face: .

Hopefully someone with some expertise see’s this and can help us out!
