So I finally finished
PONIES.
https://www.imdb.com/title/tt33270420/
It ended in a cliffhanger and as of now, there is no season 2 in the works.
Recent streamers I have watched that ended in cliffhangers with no new season approved:
Alien Earth Season 1
Last Samurai Standing Season 1
The Night Manager Season 2 (waited 10 years to get the 2nd season and they didn't tie up the loose ends from the 1st season in the 2nd season, MoFos!)
Pluribus Season 1
Smilla's Sense Of Snow Season 1.
Others:
Wednesday Season 2 (a third season supposedly has been approved)
Butterfly Season 1 (Amazon canceled the series so we will never get a 2nd season and get closure and explanations on the events at the final episode of season 1)
Series that I am currently watching that I hope won't end in a cliffhanger
Memory Of A Killer Season 1 (currently on Episode 4, final episode #10 in first week of April)
The Beauty Season 1 (currently on Episode 5, final episode #11 on March 4th)
