I think it is stated many times here, with screenshot proving facial scan and the works are in order.
There are 3 groups:
1) limits as usual (in which group you obviously are)
2) people going in for an update, might be to do the facial scan first time, might be an update because of new passport, ... Then walk out suddenly hit with lower limits, unable to change them.
3) people who up to a few days ago had the same high limits and able to change them (using facial scan to confirm changes), suddenly noticing the limits have been greatly reduced and not being able anymore to change them back to the old levels, with for example the app clearly stating that the maximum daily limit can be increased to maximum 50,000 Baht. Highlighted in red font in the app!
Plenty people from group 2 and 3 have visited their branch and called Kasikorn's K-center (with and without assistance from branch staff), and across the board got the same answer, big apologies but those are the new limits as imposed by the Bank of Thailand.
Just because you happen to be in group 1 does not give you the right to ridicule people in group 2 and 3 as scaremongerers.
It is not only here on this forum, plenty others on reddit etc as well.
