Anyone else have a problem with earnings?

I've got doge, cardano and lrc.

Last week I set my tiny amount of doge and cardano to earn with no problems I'm trying to do the same with my 900 lrc and it just doesn't work.

I've gone through the same process on mobile, clicked the max amount and subscribe after accepting the terms and nothing happens.

My app is updated and I left it a few days in case it needed to register and it just isn't going into my earn holdings.

Anyone else had this issue?
