Custom React Native components?

Hey @hari_whitebalance!

Custom components aren't currently supported on Mobile neither is accessing video as you mentioned. The dev team is aware that both have been requested I can let you know here if they're included.

You might be able to link to the mobile view of a Retool web app to do so - have you already experimented with chunked uploads in web apps? I'm not sure we support this natively but know that other users have made attempts (this thread, for example).
