Hi,
When I call a contract on Mumbai, the transactions remain pending. They are visible on polyscan, but dissapear after about 20 minutes, and are still in the mempool in alchemy.
I tried with different values for gasPrice and gasLimit. I also tried with infura and moralis and it seems to do the same.
last transaction I tried : 0x288a1d590a5e985e1681ea0a5d725a13003b0197a5e8fb2c8a2cebdacac18aec
