This bug appeared since yesterday and is rendering all of our docs unusable.
Basically, there seems to be an interface bug that is making it impossible to change any values if you are in a modal view (row expand) where the column being edited is a lookup column displayed as a subtable. You can’t add or remove rows to the subtable either.
We rely heavily on subtables in all our docs and we are completely stuck. The issue appears in both old and brand new docs. Please assist urgently.
