getting data unreliable if datapoint is large

- Arduino board: ESP32 from AZ-Delivery

- Arduino IDE version (found in Arduino -> About Arduino menu): 1.8.13 (or/and plattform io)

- List the steps to reproduce the problem below (if possible attach a sketch or
copy the sketch code in too):
Simple Sketch that inits a connection subscribes to a topic and requests that with feed->get() or gets the last data with feed->lastValue()
If you enter data of more than 80-85 characters the value is not received. (with get() it will never call the handler and with lastValue() it will never finish the call) (That is true for feeds with history turned off and on)

It also happens with the example sketch:
https://github.com/adafruit/Adafruit_IO_Arduino/blob/master/examples/adafruitio_01_subscribe/adafruitio_01_subscribe.ino

Start with examples/adafruitio_01_subscribe/adafruitio_01_subscribe.ino and trace the feed->get() and feed->lastValue() calls described in the report. Reproduce the failure with values over 80–85 characters on the ESP32 setup, then verify that the handler receives the value and lastValue() completes for feeds with and without history.
