Hi,
These are the things I done:
1) downloaded the USDJYP bot, copied the file from my downloads to MQL4, refreshed my MT4 platform and bot appeared with no issues
2) backtested the bot and made minor custom adjustments
3) went back to download an XAUUSD bot and an GBPUSD bot from the app using the same process as in step 1, however nothing happened.
4) I installed the two bots from step 3 in a zip folder, unzipped the folder, opened it and dragged the files into MQL4, nothing happened
5) deleted the USDJPY bot and tired to download all three as a zip folder, however after the process only the original bot from step 1 appeared, not the others.
6) tired installing the bots individually one by one, however the same result as step 5 happened, only the original bot from step on appeared.
