I have recently subscribed to AnkiHub, and selected multiple decks to sync. But, Anki shows an error telling me that I have reached the maximum data size to sync, and have to reduce it to sync.
I have been using Anki for many years, for language learning, medicine and many other topics. Didnโt know there was a maximum data limit.
Your collection file is too large to send to AnkiWeb. You can reduce its size by removing any unwanted decks (optionally exporting them first), and then using Check Database to shrink the file size down. (โจ475492352 > 314572800โฉ)
