ACCESS TO WORK LOST AS ZOHO NOTES SENDS ME 24 HOURS INTO FUTURE

ACCESS TO WORK LOST AS ZOHO NOTES SENDS ME 24 HOURS INTO FUTURE

Hi - on holiday and my phone took a while to adapt. I'm still in the same timezone, but Zoho synced, with tomorrow's date on the timestamp (It's the first of August now; timestamp said 2nd August)
All the notes I was working became inaccessible.
I had to do a complete wipe of the app cache and reinstall of all my data, on some stupidly expensive roaming tariff 
That took me back to the previous save, but all my updates were lost.
I love the style and features of ZOHO NOTES, but it does need to become more robust very quickly!
