I have successfully upgraded on Linux and Android, but on iOS I am stumped. Following the Everdo iOS app’s instructions, I share the .key file, selecting “Open in Everdo”. When I do, I am returned to the iPhone’s home screen. There is no informational or error message. When I reopen Everdo, it tells me I am still on the free tier. What might I try next?
I am on Everdo 1.3-3 on an iPhone 7 running iOS 13.6.
