Please consider am new to all this: I had to replace the SSD on my TBM and after being able to login back into the device from umbrel.local I can see the btcCore sync restarted but the amount of the BTC wallet it’s not displayed:
It’s normal that the BTC wallet balance is not showing after changing SSD? shall I wait until the btcCore sync is completed or I should do something else in the meantime?
Exactly. Patience is the key. The initial catching up blocks could take a while after a shut down.
The best way to check is to look into bitcoin logs. Until bitcoin core is not up and running correctly do not do anything else stupid.
