Link without language parameter: https://developer.android.com/tools/adb
Link-Preview somehow forces the Portuguese / Brazilian language. Is the server located in Brazil? And can this be deactivated somehow? For example, the German language is not forced when I enter the page normally in the URL line of the web browser.
maybe via header:
Accept-Language: de-DE,de;q=0.9,en-US;q=0.8,en;q=0.7
The Android developer page does not have a German (de-DE) translation, so English is selected.
If the server sends pt-br, Potuguese - Brazilian language is selected.
That’s weird, we didn’t have that with any other embeds yet. This will need more investigation
Accept-Language header is not sent, then I don’t know exactly what google is doing there either
