When I use Twidere app (a free Twitter app) I can’t zoom in (nor out) pictures. When I open the picture in any browser it works.
It is not quite the same error that is mentioned in https://forum.fairphone.com/t/fp2-zoom-with-built-in-picture-viewer-broken/12952
In my case most pictures are shown too small. On my old phone (OnePlus One) Twidere worked fine.
Any hints or workarounds for this?
