Suddenly, from a week or so ago.
LR Classic (on Mac) has initially very hard time displaying previews from iPhone, some are displayed randomly, others grayed out...
Selecting one or several, the result is the same: the import progress bar appears (but doesn't move) and the central part displays "Importing photos" message... but nothing happens. It stays like that frozen for many minutes, until I manually cancel the import.
