Sorry that you are experiencing this issue. While we do not officially have iOS support on the forums, it's interesting that it works for you on the English forum, but not the German one. Is it possible to attach a screenshot of what you are seeing?
THank you in advance,
Was out of the office - and I can't post screenshots from the iPad...
here we go:
image 1 shows 'Yesterday' as latest activity
image 2 shows that there is an activity today...
image 3 shows how it looks when trying to post or to answer - there is no entry-field
I will forward your screenshots to the engineers.
Thank you again for the screenshots. The engineers have seen and acknowledged the issue. We don't have a fix schedule yet, but I believe this will be addressed.
