trying to share a picture from Riot to WHatsApp fails with file format not supported

[AmandineLP]

steps: long press on a photo in Riot, select share, select WhatsApp -> whatsapp opens and shows the error 'format not supported'. Probably a problem on WA side who is limiting the file format but maybe we do sthg unexpected on our side?

Ok, thanks for reporting, I can reproduce the issue, by sharing with WhatsApp, with GMail, with anything actually.
I'm investigating

The decrypted media is deleted during the time you select an application to share with, because the application is going to background. If you're fast enough (< 4 s) to select the application and do other(s) step(s) before this third party application request the media (ex: select a group in WhatsApp), it works well.

I'm wondering how to fix this issue properly.
