Yup, we’re experiencing a bit of this as well, although not as extreme
– A flexible content canvas that contains multiple flexible content blocks, each of which can have 20 – 30 ACF fields of all types (checkboxes, repeaters, wysiwyg, taxonomy choice, etc)
On the more complex pages (15 or so content blocks), it can take up to 20 or 30 seconds to update. Would really like to get a handle on this as we’re right on the line between tolerable and intolerable.
