STrange Behaviour on multiple forms

Is there a problem with the Jotform Servers?  Many of my forms are behaving strangely?  Previously working forms are now non-responsive and query strings are not being passed correctly into the forms?  Also experiencing errors on collapse fields and conditions?

We were informed that the issue was solved , please let us know if it still continues in your end.

Yes thank-you.  Appears to be Ok now.
