Chapters not being marked as read [Fixed]

[idontgatcha12]

As the title say, currently I'm facing a problem with chapters u read not being marked as read.

When the server is under heavy load read markers may end up being delayed, that is, they aren't lost and will eventually get applied, even if that were to take several hours.

It's been happening to me as well...

I got that too tried doing mark all chapters as read to fix it but it changes it back if I refresh the page.
Edit: Although as mentioned above it does seem to fix itself eventually
