Tchap web session will not exchange keys with iphone

[estellecomment]

• user has an iphone 2.0.5 session (no other sessions)
• user starts Tartine session
  • Tartine requests keys from iphone 2.0.5. → KO. emoji exchange starts, then error on mobile : "la vérification a été annulée : motif unexpected message"

Edit : this does not happen every time. Sometimes it does work.

It was already a problem in web v2 (reproduced)

the verification request seems to be sent to v4 but the iphone 2.0.5 does not seems to receive or to handle the request (cf. logs from v4 that seems to send the event)

Is is not related to the issue https://github.com/tchapgouv/tchap-web-v4/issues/203 instead ?

A workaround seems to be :

• start the verification from the iOs device : WORKS
• start the verification from the web device : does not work

[odelcroi]

There are still problems :

❌  Web 4.2.1 < iOs 2.2.3 (olivier)

connect to iOs, ecrire quelque chose dans un salon chiffré connect to Web ⚠️  Le web se plaint que l’appareil n’est pas vérifié, cela semble bloquant Faire les verifications entre les deux appareils, en la lançant la verification depuis iOs. La verification fonctionne mais le web se plaint toujours de ne pas être vérifié. Meme en essayant de clear les cache. Les verifications échouent. ⚠️  Il semble que le web n’arrive pas à se vérifier avec l’appareil iOs

is it related now to cross-signing keys not trusted by the verifying device? See https://app.crisp.chat/website/6dacc68e-de3a-4511-8177-1339616098de/helpdesk/articles/fr/371f9f37-92f1-4bcf-8730-1e0899049f27/
