[Story] EX: Incoming device verification request

[manuroe]

Description

• As a user
• I want to use EX to verify a new login that happened on another matrix client.
• So that I can verify any new login using EX instead of depending on another matrix client like EW to do so

Any ETA for how long this might take to implement, no intention to rush anyone I kinda screwed it up because I uninstalled the main element app on Android, and after an update to Element on Windows...the Ex is the only one with device verification and access to past messages.

I expected at least the Windows one to retain verification and messages before but now its all gone.

Hi, it shouldn't take particularly long but I can't speak to exact timings. Meanwhile you might want to have a look at setting up chat backup and a recovery key, which you can then use to verify other devices and retrieve your keys.

Everything in Incoming Device Verification Requests Testing Session is cleared.
We can claim the feature beautifully done and tested 🎉

It was already available in EXA 0.7.3 and EXI 1.9.5. It is fully done in EXA 0.7.4 and EXI 1.9.6 with all the little improvements we wanted to apply.
