I just noticed this issue today. I thought it's their June 2026 app update that caused it but turns out they added google play integrity API long ago. My session was just still signed in. Sometime last week the session expired and I'm no longer able to log in. I can of course log in via Vanadium but that's even more clunky than their app. I made a ticket and told them this is a bad app development decision and makes airalo unsuitable for the ever growing cohort of security minded GrapheneOS users. They wouldn't budge so I did the right thing and told them to cancel the account. Drop in the ocean small biz account that turned over less than $100 a month but the message has to be sent.
Nomad works on graphene but the free trial will fail on graphene because they can't fingerprint the device well enough.
Ubigi works well on graphene and is better for business anyway. Switched to Ubigi.
The enshittification continues... 😓
