I had 2 GRIN TXs on Gate.io about 9 weeks ago for almost 9,000 GRIN.
They were withdrawn to my Niffler wallet but the TXs were pending for 3 days so I canceled. The coins never reappeared in my Gate.io account and I have contacted support so many times. They just keep telling me to be patient. Patient?! LOL It’s been 9 weeks!
As I understand my GRIN can’t be lost but I can’t use the hedwig TX ID to find it on the block explorer, or at least I am not doing something right.
try do it in niffler wallet:
go to rightup corner of niffler wallet “more” → “check balance”
after check balance, if your blalance is the same as before, so the tx is never successful and you coin is in gate.io
