The workaround is not a workaround. If you can't use realms, you won't be able to upload your world to other devices. I can't believe this deadly bug has been left for two months.
I am experiencing the same issue, version 1.14.4, no fish, no squid no dolphins, only turtles and drowned. I see this issue is labeled as resolved, but I don't see any actual answer as to what I need to do to solve my issue. Please make what I need to do more clear so I can understand how to fix this issue, thanks.
There is no mention of when 1.16.2 will be released.
