Anyone who has had to contend with the learning curve of InDesign and the high cost of it, may find Affinity Publisher to be a great alternative. I have. It integrates with existing photoshop files as well and Affinity Photo is also an excellent alternative to Photoshop.
PS They don’t offer affiliate marketing. I’m just sharing … I discovered the programs when I also found out that Mac OS Systems – Catalina and Big Sur – would not be supporting the old 32-bit software anymore (These are 64-bit and work fine). And if you’re like me, and are budget minded, I didn’t want to pay Adobe high prices to rent their programs; you may want to look at these.
