From the Home Screen, tap the cog icon in the bottom right corner to open the settings page. To view transaction limits tap on 'Account limits':
This will display your transaction limits imposed on bitcoin lightning network transactions (Lightning Payments) as well as a separate set of limits imposed on both, bitcoin on-chain transactions plus all fiat (GBP/EUR, etc) transactions (Global Payments).
Daily Deposit Limit
(Limit on the amount of funds you can deposit in a single day)
Daily Transaction Limit
(Limit on the amount of total funds you can send in a single day)
Deposits per Day
(Limit on the number of deposits you can complete in a single day)
The progress bars beneath both your Global Payments and your Lightning Payments are an indication of how close you are to reaching your transaction limits. If it completely fills then you have reached your daily limit and will have to wait until the next day to start sending/depositing funds again.
