Today I found possible little bug on Upwork.
When I am trying to apply to fixed price job, Upwork say me that I need to increase my hourly rate more then 3$/h, but really I have now 18$/h (also whole rate is does not apply to fixed price job).
I am found temporary solution for this case just reset my hourly rate to other amount then return it to original hourly rate.
After this I see that all working ok.
Does anyone still watching these difficulties?
