So maybe someone knows the answer to this. A few days ago I rage quit Riot.im/matrix.org and lo and behold 2 days later they release an update allowing cross signing to solve the friction with regard to verification. So I tried to test it out. Turns out, if you have no active session you cannot ever verify your sessions again, apparently. Unless there's something that is not so apparent?
Does anyone reading this know how to verify your only session in Riotx or riot desktop?
