UC Mini Apk Speed Mode not working.

Hello all,
Please help me troubleshoot this issue. I am using a old version of the UC Mini Apk version 10.9.8. The speed mode which enabled heavy data saving through compressing the web pages has stopped working and loads the default non compressed version of web pages. How do I resolve this issue? Previously when such a problem occurred, I used to turn of the cellular data option and get a error page in the compressed speed mode and then used to reload the page then which used to fix this problem but it no longer works. Any suggestions would be highly appreciated.
