Hi @Amefuri! Thanks for reporting this bug!

Hmm, that's interesting. I wonder if that dispatch delay is causing an issue.
Maybe if you can, try commenting out the dispatch_after line (And the subsequent }); one too) and see if that fixes it!

I'll try and look at it when I get the chance, but if you can try diagnosing the problem for your own use case, that would help a lot. :)

Thanks!
