TLDR : Answer Summary
The issue with Kasikorn Bank's app and debit limits seems to have been resolved. Users can now request an increase in their debit card limit via the app, with approvals taking around two days. Users can increase their limit up to 200,000 Baht per day for both debit transactions and app usage. However, some users have encountered rejections when trying to increase limits either at the branch or through the app, suggesting that there might be some restrictions or a monthly limit on attempts.
