I had exactly the same problem and my posting schedule was a complete mess. Then I started using
https://getpin.com/solutions-en/regular-posts-en/ with Getpin, and it honestly changed everything. From my personal experience, scheduling posts from one calendar is a huge time-saver. I now plan all my content for the week in one sitting, and everything publishes automatically to Instagram, Facebook, and Google Business Profile. No more missed days, no more rushing to post something last minute. My engagement became more stable, and I finally look consistent online. If you struggle with regular posting like I did, I genuinely recommend Getpin.
