Seven deadly sins 4th season?

I'm now done with the "4" seasons on netflix but actually only 3. That's why I wanted to ask when or if there will be a 4 season?

Yes, another season is planned although the "4" season was not a great success, as many of the scenes were badly animated according to the opinion of many viewers, but it could still be 1.5-2 years before we see the "5" season to get.

I understand thank you
