There has been a flurry of services in the EU that handle these things for you, if you are impacted. It's usually as simple as 1 form + a pic of a boarding pass, wait ~3 months and get ~70% of the money into your account. Exactly as low effort as needed to make it both useful and (one would hope) incentivise the airlines to sort it out in a better way for the client (i.e. rebooking, vouchers, etc).
