Attempt to open pdf attachments only leads to the app chooser window offering navigation apps

[Alxa 482]

Hi there, I stumbled over a bug on 10.46 when trying to open a pdf attachment. Normally the in-app view would launch (bad to not being able to chose a decent pdf viewer but at least I could look up the content without downloading the file to the device). Now when I tip on a pdf attachment the Android app chooser launches (I cheered for a moment!) ... but it only shows navigation app (apps normally opening upon gpx-files). Access to pdf gone - only workaround: download. I see this behaviour on multiple devices on my account. Other apps on Android open pdf regularly.

Can anyone confirm this?

PS: I raised a ticket# 3631765
