Description

Inline results work differently then in android or windows client. I am developing an inline bot. I currently have over 10000 users and ios users say that they cant preview content of my bot (images and voice messages)

Expected Behavior

Image inline result: should open in full screen mode before beeng sent
Voice cached inline result: should have a play button

Actual Behavior

Image: The picture is sent without preview. Only the thumbnail is shown.
Voice: There is an empty square with the first letter of the name

Steps to Reproduce

1. Create an inline bot with voices and images
2. Try to use it
3. Understand, that this is very difficult without beeng able to preview the content
4. You can also try it in @vosticksbot (voices) or @pic (images)

Voice expected (screenshot from android):

Environment

Device: iPhone/iPad X

iOS version: 13.X

App version: 7.X

I don't have an ios device, only screenshots and complains from my users.

Start by reproducing the issue with @vosticksbot and @pic, comparing the iOS behavior with the supplied Android screenshots. Trace the inline-result handling in the iOS app; done means image results can be previewed full-screen and cached voice results show a playable control before sending.
