Unable to Swap or Withdraw
Osmosis has the ability to use many different gas tokens in lieu of $OSMO. However, there are some tokens that are unable to be used.
If the system doesn’t see any valid gas tokens in your wallet, the ‘Swap’ button and withdraw options will either not load or present errors
The below image is an example of an error message shown during a withdrawal when no gas tokens are detected in the wallet. There is not an indicator that this is the problem, so it can be quite tough to determine that this is the cause

Otherwise, when trying to perform a swap without any valid gas tokens, the ‘Swap’ button will remain unclickable

The solution is to add a compatible gas token to the wallet. The easiest would be to have $OSMO so there wouldnt be a need to change any gas settings.
If you are still experiencing withdrawal or swap issues after ensuring you have tokens for gas, make sure you are using Chrome browser. If already on Chrome, try fully clearing your browser cache+cookies. This can be done with ctrl+shift+del or command+shift+del on mac, and selecting cookies and cache from the menu

If using a VPN, try turning it off, or setting a different location.
If swap or withdrawal issues still persist, you could try some of the alternative deposit/transfer options available – often times using an alternative dashboard to transfer your tokens or swap will circumvent issues
