With 3.7.14.50440-fc36 (Fedora 36), insync start gives me:
Insync headless is not included in your “Developer Sync/Developer Sync/Developer Sync/Developer Sync” license. Visit Free Trial and Pricing - Insync for more info.
This means I cannot sync any more, because the daemon does not start. I think this message is doubly wrong: I do not use insync headless (but the ordinary client, as I always did), and use of insync headless should be possible with workstation licenses, shouldn’t it?
