[1st of April 9 am EET] Instagram posting should now work normally. We are still monitoring the situation. Once again sorry for any inconvenience.
[31st of March 2 pm EET] Unfortunately, Instagram has problems and direct publishing (with video) does not work properly. The issue has been reported to the Instagram engineering team and we are investigating it currently.
We will notify you as soon as we have more information or an estimate for the fix. Posting to Instagram with pictures and using notifications works normally.
Sorry for this inconvenience!
