_Type_: Bug
_Summary_: Extension command and its chat message is not shown after user installed the extension and relaunched the app if development mode is OFF. If user tries to install extension again by tapping on its placeholder message then popup is shown that extension is already installed.
So, in order to have extension working user needs to turn ON development mode. Because user can install extension by scanning QR code or by tapping on extension's message in the chat (e.g. for Gfycat) and have no idea about development mode we need to warn user about setting development mode on or find other solution.
We also might add some info on the message placeholder "To see this message install the extension" to inform about turning on development mode.
So, there should be solution that explains to the user why extension is not shown even if it's installed for 2 cases:
after user relaunch the app:

@rachelhamlin I suggest showing the message if dev mode is off, something like "To be able to install the extension you need to enable dev mode first in your Profile under Advanced", wdyt? could you help with the text of this message?
Hmm. Tough one. If the user enables dev mode and revisits this chat, do we then display the install extension message @flexsurfer?
In that case, I'd write: "Please enable development mode in advanced settings (link to profile)." [Option A]
Better yet, if we can deep link to the advanced settings section directly, "To see this message, enable development mode (link to advanced profile settings)." [Option B]
@rachelhamlin or we can show popup "Enable dev mode and install" "Yes" "No" , in this case, we just enable dev mode when user press "yes" and install the extension
Oooh that would really be best @flexsurfer. We don't need design for this, do we?
@rachelhamlin we don't need, we can use a standard popup, I just need a text of this message
Maybe something like this @flexsurfer?

Confirm Install
Development mode is required to install an extension. Do you want to enable and continue installing?
OK Cancel
can reproduce on release 0.12.0 build 13 both ios and android
seems like there is some specific case when it can be reproduced, so assigned to myself to investigate more
can't repro
