Is it possible to share an e2ee encrypted folder?

Thank you Freedim for the detailed workaround but it didn’t work for us at step 4.
“Then first B syncs, then A syncs so that A now sees the shared folder as encrypted (green padlock).”. In our case, A does not see the shared folder as encrypted.

We are using NC 2.1.0.1 Snap, End-to-End Encryption 1.7.1, Default Encryption module 2.9.0 and the latest NC desktop client 3.2.2.

Thank you very much once again.
