In a another world with my smartphone Next Chapters
I was up to V9 part 7 I think and all of a sudden all links to next part state It is not available any longer. I can still se Part 1 for each volume, but anything after nothing. I tried another title real quick and it worked and could see Part 2.
@cbrtlsseca That series was on catchup for December 2020, now that it is January 2021 the series has gone back into the vault and the new catchups for this month are available.
As @jpwong has said it is no longer part of the catch up meaning if you want to continue to read it you will need to buy it or wait to who knows when it becomes available on another catch up month.
