The number of users and transactions that continue to increase makes the BSC network very busy, it's been a few days when I swapped on Pancake then the results were very slow and I had to repeat it again so that it made a double fee when I checked on bscscan, if gas costs go up it should make the speed stable because they get more and if this problem can't be solved then there will be many problems in the future with BSC.
seeing what you have experienced, of course it is very unfortunate that it happened and it is very likely that you are not the only one who has experienced something like that,
For BSC, of course, this is homework that must be completed immediately if users don't want to be left behind
