Glad to hear that Instagram is working for you again, Gwen. Sadly, even though I am using the same versions of the plugin and helper as you, the same amount of memory as you, but a newer version of PHP — 7.3.1 — autoposting to Instagram still does NOT work for me since the third week of February of this year. All I can do is hope that Ludwig will eventually figure out what is going on, because I am not convinced that the problem is on my end. In fact, a few minutes ago, the plugin said that my test post was successfully posted to Instagram, but it is nowhere to be found. I really don’t know what else to do.
