Why creating a transaction proposal lock my balance and is significantly higher than the proposal amount?

Because it locks the inputs which usually do not exactly match the output amounts. For example, if the input is worth 50 BTC but you only want to send 25 BTC, Bitcoin will create two outputs worth 25 BTC one to the destination, and one back to you ( change ). Then 50 BTC gets locked until the transaction is broadcasted.

Copay requires high fees for low amounts transactions?

There is not an issue there. The parameter used for the fee calculation is the TX size, not the output amount. So, this could happen when you have many small inputs in your wallet, so you need to use all (or most) of them to build the transaction and your fee will be increase significantly. For a more detailed explanation check this contributor comment: https://github.com/bitpay/copay/issues/5164#issuecomment-265569494. This could be useful too: https://github.com/bitpay/copay/issues/4803#issuecomment-254496226.

I always get "Insufficient funds for fee" when trying to send?

This happens when you have insufficient funds to pay the fee amount of the transaction you are trying to send. It could be possible that you have a ton of very small inputs that are no economical worthy to send (check: https://github.com/bitpay/copay/wiki/COPAY---FAQ#copay-requires-high-fees-for-low-amounts-transactions). You can get an idea of your "usable" balance by trying to send all (using the send all feature) funds to other wallet.

If copay.io disappears. Is there a procedure to recover my funds?

It is possible to recover funds from a Copay Wallet without using Copay or the Wallet Service, check the Copay Recovery Tool - GitHub. All you need is File/Text Backup or Wallet Recovery Phrase (12 words).

Transaction History: "clear cache"?

The transaction history and every new incoming transaction are cached in the app. This feature clean this up and synchronizes again from the server.

How can I get my Wallet Private Key?

You have two ways to obtain you private key:

  1. Visit https://bip32jp.github.io/english/ and paste your BIP39 passphrase ( Copay 12 words backup ). Then, you could get your xPrivKey on the BIP32 Extended Key input.

  2. Go to Settings -> Wallets -> Choose your wallet -> More Options -> Export Wallet -> File/Text -> Set up a password -> Download 

Then, go to https://bitwiseshiftleft.github.io/sjcl/demo/. 
 Open your file and copy the whole text. Paste the text in Ciphertext text area. 
 Enter your password on the Password input. (that password is the one that you enter in Copay)
 Then click in decrypt. 

In the Plaintext text area you could find the xPrivKey.

Amount too low to spend

This warning in incoming transactions is shown when the received amount is too low compared to the current Bitcoin network fees. When trying to redeem this amount in the future, it could happen that the fee required by the Bitcoin network to include it into a transaction will be higher than the amount itself, making it economically inviable to use it.
