I also did not see any such news where delisting is mentioned. But many are thinking that it might be due to regular maintenance. Moreover, if it was specifically mentioned which coins have been delisted and which exchanges then the matter would have been clear to everyone.
Looks like the OP is just bragging about this, none of us all responding to this topic got any information regarding the Polygon Chain delist. Moreover he was also never seen again after he created this topic.
Overall this Polygon chain is quite popular now and in future it will overtake Previous ATH. Moreover, the investment on this project is constantly increasing.
This is OOT (IMO), but I wanted to make a little statement about this.
Do you think Polygon can reach its ATH once again after The Merge that happened to Ethereum? A lot has changed in Ethereum, especially for Fees, since The Merge happened.
In the past, people moved to Polygon which is Layer-2 due to very high fees on Ethereum, but because of The Merge, fees on the Ethereum network are no longer high. For me, there is no more room for Polygon to rise.
