Free share referral button not working

I signed into my account and clicked free shares, it said to first top up £50 which I did, it than have me the free share screen which just had a continue button but if I click Continue it does nothing. I’ve waited, pressed a million times and nothing.

I withdrew the money

Went back, said to top up £50 again so I did that. Clicked free shares and it said top up £50 again!! Not even giving me the continue option now!

No idea what’s going on! Please help :frowning:
