Hi menion
while logging a TB without comment red label "log failed" apeares.
I think a label with hint e.g. "missing comment" will be more helpfull
Ah maybe this is problem caused by some changes in groundspeak API. I remember little bit that they announced something like this ( disabled support for empty logs ). Thanks, I'll fix it.
This behavior has been around for quite a while already, I recall running into it at least a year ago.
Don't think this has been newly introduced with an API change.
What helped in my case was to add some of these variable placeholders like date, found counter etc.
As these get populated automagically the form field will not be empty.
