Have you tried to change a browser? if panjul07 instruction does not work (but I know it will becauze I just tried it right now and it worked) try to use another browser like brave as it's now supported of playbetr.
Thank you to itsmylife and panjul for your responses.
asu you should be able to type in the number you want to wager as panjul has stated. Please let us know if you continue to have an issue here or by going to www.Playbetr.com and then clicking the support tab.
Basically the number of users experiences difficulties while using browser is still low. Most issues are from those who are using Brave browser while it seems not a problem anymore. Having android application is good but it is not that good for gambling activity. Using browser such as Chrome, Firefox, Opera is still much more better than using android application IMO. I believe most gamblers especially those who used to play big amount will still prefer to use Desktop for their gambling activity instead of using their mobile phone.
