Thanks for the prompt response. I upgraded to 21.0.3 on both devices and tried again but have the exact same issue. I have zipped up the file and sent it to the support email address on your website. I have also included a bonus bug report :-) (recalculating G values crashes the app in my case) Chee...

I'm using V21.0.1 on 2 phones (have checked version on both) and having identical issues (failing to import on new phone with same error messages as above).

Would the manual workaround still be worth trying or is there possibly another issue?

Cheers - N
