Need something achievable for an extremely tech illiterate person on iOS. I got told about this after they are already gone and have no access to the device, but am asked to solve the problem.
EDIT: (SOLVED) Signal was super easy, works awesome, and was easy even for my mom to figure out on her own. Thanks
They asked for any cross platform messages app, not an iMessage bridge. I’d say Element
Oh oops, my bad - I misunderstood the question…
Don’t blame yourself, it was extremely poorly worded and unnecessarily confusing.
