Seems a new issue today - we had to complete a captcha for security and then we can’t view the Grid on our Portal now, unless we zoom the browser window out.
I logged a Report via our Dashboard. I changed the Grid to a List view on my Test Site and that works fine.
Thank you for bringing this issue to our attention. Please be assured that we have created a ticket for this issue and our engineering team will investigate it as soon as possible. We’re glad that changing to the List view works fine as a temporary workaround. We’ll keep you updated on the progress and any potential fixes.
We apologize for any inconvenience this may have caused and appreciate your patience while we work on resolving this.
We sincerely apologize for this inconvenience! The issue has been fixed. We apologize that this was not fixed quickly. We will improve our process in this regards.
Hi Abdul - appreciate the error being fixed. We did have a number of complaints, but hopefully we’ll smooth things over. The addition of the freeze field is a very handy improvement which will please all of our Clients!
