Dead on iOS 27.2 BETA

I love this app and used it every day until I upgraded to 27.2 beta. Now the app will not stay open. It is completely broken in this condition.

Need to share a folder instead of a single file

Will be better if I can share a whole folder outside the ‘sandbox’ thing, which has been implemented by ‘sycnthing’ system, so the last star is preserved for that gorgeous update in the future. Good app by the way…
