Samourai Balance

I’m experiencing similar syncing and balance display issues people have posted on this forum before, but none of the suggested remedies work.

My first transaction to Samourai worked perfectly, but the second transaction didn’t appear on the home screen of the Samourai app on my mobile phone. It does appear on the desktop whirlpool gui. As a result I get a ‘broadcast error’ whenever I try to send from my postmix wallet. I tried the XPUBS, addresses & blocks tools in the Dojo Maintenance Tool, but to no avail.

Does anyone know how to fix this? Any help would be much appreciated!
