Blaze has not Synced since 18/04/17

I've just had a short holiday and let the health stuff slide a little or would have noticed this earlier.

Seems my FitBit Blaze has not synced since 18 April.  I believe this means the likely culprit is the latest app update?

I have a Samsung S5mini.  I have tried restarting the phone (both restart and power off) and the Blaze several times (left button and bottom right simultaneously).

I get the error message "Tracker Not Found" and that is all.

I'd appreciate if anyone can assist and advise.  Cheers.

Did you try uninstalling the app, rebooting the phone and then reinstalling the app?

Thank you.  I had not tried that yet.

Somehow the problem has resolved itself overnight and the Blaze is syncing once more.

Not sure what was wrong, but as long as it is working..
