I switched over to TickTick when Todoist suddenly changed their pricing model a few years ago. I don’t remember the specifics of what happened but I remember being very frustrated with the sudden changes as it would’ve required me to change my whole system.
I’ve been very happy with TickTick since then and would strongly recommend OP checks it out to see if it fits their needs.
