Im using UCBrowser version 7My Tempermonkey version 4.5
I haven't tested the script in any mobile browser. Is there a way to extract script error information, an error console of some kind?
You could try rolling the version back to 1.8.3 (before using asynchronous functions). This site doesn't keep old versions but you could try this link:
Sorry, I just realized you were talking about a different script, so never mind on the link in my previous reply.
