I haven't seen anything that would indicate LDA is off the table. The opposite actually... The DD period for LDA to look into IQST passed months ago and they have since continued to reference LDA multiple times even referring to it as a partnership.
They have also confirmed they are working on an acquisition that could close anytime now, so we know DD on the acquisition has already started. They wouldn't move forward working on an acquisition if LDA backed out after their DD period.
It stands to reason that LDA is willing to work with IQST (purchase the bond) but since the first 5M is specifically for an acquisition, they are not finalizing the deal and providing the funds until the acquisition is confirmed. DD on the target acquisition is likely the delay, and that is common.
