I wouldn't worry too much, I imagine Saif probably just is busy and focused on B4XDatabase. After all, he gave the forum a launchdate for the launchdate
, which was December 26th, 2021. (I don't think I saw a date posted by him at that date though, but I can have missed it - I don't read all posts.)
In the meantime, I'd recommend you starting a new thread for each project and see if you can get help from other people who purchased those solutions. The more specific you can be with the functionalities Saif promised, and that still is lacking, the more likely somebody will be able go give you concrete help and advice.
As for the new version of the VPN project, somebody else might have it and you could perhaps get a copy from them if you show proof of purchase in a DM. (I think I've seen this happen with some other of Saif's projects.)
