Hello,

We’re looking into this issue now. Even if it’s weekend this bug needs attention from the developer team.

I'm Getting the Same Issue and We start our new Season Tomorrow, I must be able to send out the Seasons Rules and Edit the Info for the Two Compounds to be used. Please sort this as soon as you can

Same here

I’m not exactly sure if ppl are still experiencing this bug or if you guys have fixed it.. but since this morning and doing what gert rose suggested, i managed my activity list on the browser (desk top version). Then after I got back on the app and my problem is solved(I can click edit league). You guys might have fixed it and I don’t know it yet tho. 
Thanks again guys for looking into this, if the problem is still occurring for other tho. And also thank you gert rose for the work around helped greatly:)

Yep, Sorted now, thanks

Hello,
